Ok, A little backround. I know hardware and networking. I can build just about any config of a computer. I understand overclocking and undervolting. I can invest around 2,700 for initial investment. So do I buy hardware to build a GPU miner with at least 6 cards or more? Probably RX580 as they are cheap and I have one in my rig. More on that later. Or do I a Asic miner like this I understand a GPU miner is multiple coins and not Bitcoin, and Asic is nothing but Bitcoin. I've done the math on the Asic miner and the ROI in about 3 months with a net gain of about ~10,000 USD a year @ .13 cents per Watt. I've had a hard time finding a solid or semi way of calculating the earnings for a GPU miner. Not only because it is many coins or dedicated to one coin, but there our other variables involved. However I have more control of the hardware if it fails. I dipped my toe into mining with my own rig that has a RX580 fatboy and a AMD Phenom ii x4 955 black edition. I overclocked the GPU and undervolted the CPU to reduce heat since it was hitting 62 cel. The GPU gets 12.5 sol/s and the CPU was getting ~322 h/s. All this added up to ~170 watts and a net of .00218322 BTC/Month. This was all done using Cudo as it was easy to find and setup just to test. This was just a test to see how it would work. I wouldn't use Cudo to full scale as it is a pool and the transfer to a Wallet is pretty steep in relationship to earns. I understand that in a pool you get your share based upon how much of the "work" you did to get find block. So do I build or buy? With that much computation power do I need to join a pool? What software is best for pool or alone? I am comfortable with CLI as long as it's well documented, but would like a remote GUI. Also what is the best wallet with the best fees for transactions. Currently using uphold since I use Brave. I think I covered as much as I could, if you have any questions let me know. Any advice would be great. If I should post this else where let me know please or I could just cross post it. TIA. Be safe, stay safe! Edit: Words and BTC earning was WAY off then I first typed this.
Edit: Thanks for all the discussion and support! I truly believe in bitcoin and the fact that I now have .0302 make a me happy 😁 I have made a total of .0002 bitcoin in ~36hrs using btc.com pool. Hash rate avg 14th/s. I honestly thought it would have better btc revenue than ~$1/Day not including power consumption. Am I doing something wrong? I also noticed other coins produce higher mining returns should I be mining alt coins with S9? Any suggestions? Thanks!
I am working with a friend to set up a bitcoin mining rig our university. I'm a business major, but my friend is in engineering and has unlimited free access to a 220v power supply. Would it be worth buying 100 AntMiner S9's on eBay and making our own rig? The math breaks down as follows according to https://www.cryptocompare.com/mining/calculatobtc?HashingPower=1350&HashingUnit=TH%2Fs&PowerConsumption=137500&CostPerkWh=0&MiningPoolFee=1 1350 TH/s hashrate (with 100 S9s at 13.5 TH/s for each unit) Electricity cost is zero. Predicted payout is $3,390/month. Am I missing something? It seems too good to be true, making 4k/month with only 10k up front. EDIT: Assume the rig was well hidden and not discovered for a few years.
semi-quick answers to common questions of new people
so people often ask similar questions over here and because they are getting probably kinda annoying over time to many I just try to answer as many as I find. if you have more that would fit here, add them to the comments
can I recieve coins without the ledger being connected to a computer
how does that work?
basically crypto currencies work like a bank-only currency, all funds are in the Consensus network which basically works like the bank of the currency, they carry out the transactions and verify you are not trying to overspend. all transactions are basically in an accounting book which is referenced to check your currency balance (which is the blockchain)
tldr: does your debit card need to be online for your account to recieve funds? nope.
I just sent/recieved coins, why are they not showing yet?
as the cryptocurrency's bank while being central to the currency (as in no currency can ever leave the network) the bank in itself is not a central institution but anyone can be part of it, and one of the major things that need to exist because of this is Consensus, or in plain english: agreement. because of this, a few blocks need to pass so nobody can manipulate the chain by calculating a different chain that overrides a transaction with a different one (double-spending)
tldr: the network of many needs time to agree whose transactions are processed in what order and therefore need a bit of time
(which in case of bitcoin is typically an hour after the transaction has set into a block)
my transaction does not get into a block
chances might be your fees are too low, while you cannot directly fix this in Ledger live, other wallets allow you to send another transaction with the same "transaction number" (aka nonce) and higher fees which as soon as it gets placed into the chain, invalidates the old one as each number can only be used once.
my bitcoin address changes everytime I try to recieve in Ledger live, is that normal?
yes. it is a privacy mechanism of the standard of how ledger generates addresses, basically allowing you to stay a little bit more private.
you CAN use your old addresses if you really want but it is obviously less private
how does that work and how do I make sure the address is correct?
simply said: complex math. if you for example enter "my secret -> Bitcoin 1" into the sha256 algorithm you get 3f667104b9efdc247d860a35d9343ec2af6adf16ee87d44bcd4a6c2af572bab8, if you however enter "my secret -> Bitcoin 2", you get 58f5c09c46585dca9bf50b2d3beb48766254138c1f89df8111cf7e012b4d7004 which cannot easily be correlated to each other, it's the same concept but more complicated.
for verification, plug in your ledger when recieving and verify your address by using the Ledger's display.
do I need to backup my currency keys often?
nope and in fact there is nothing to backup except your seed phrase. Ledger uses a technique called deterministic wallets, which allows your secret and a standardized sequence of math operations to determine your keys addresses and everything.
the above answer literally illustrates the concept, where you would throw your secret and data about which currency and the how many-th account you need into a complex piece of math and get your data out.
TLDR: all you need are your 24 words.
can I create hidden wallets on my ledger which cannot be easily accessed?
sure. but be warned, THIS IS ADVANCED.
there is a feature called a passphrase, which you can add onto your 24 words (which is why it is sometimes called a 25th word, but it can literally be anything), which works as a way to create a new set of addresses. however unlike your 24 words, there is no checksum and as it can literally be anything it is case sensitive and everything, so be careful when noting it down.
you can either attach the passphrase temporarily (gone when you turn off your ledger) or set up a second PIN with that passphrase stored on your ledger
HELP: I lost my:
if you have your 24 word seed (and passphrase if you use it, you can just reset by entering 3 wrong PINs and recover
if not, sorry, your assets are gone, so KEEP A BACKUP OF YOUR SEED
Ledger Passphrase PIN:
if you have your passphrase, just enter your main PIN and re-attach your passphrase
if you have your ledger PIN, you can move away your coins to an exchange or a new seed (which you either initialize using a second ledger or you use a software wallet for the short term while being SUPER careful (or as a compromise, new 24 words you generate offline) and transfer your funds over there, in case you used a software wallet or an exchange, reset your ledger afterwards and create a new set of 24 words and transfer back to them.
in case you use a passphrase you either need both PINs or main pin and passphrase
in case you do not have the above, it's sad and all is gone yet again.
if you have a passphrase PIN and you know it, you can TEMPORARILY attach a new phrase to your ledger to get new addresses, switch back to the passphrase using your PIN and send the funds over to your new passphrase's addresses.
if not, be sad.
Ledger Live Password
you can just reset ledger live. ledger live is just an application to watch your currency and prepare transactions for your ledger to sign. its contents LITERALLY DONT MATTER
if you dont need the privacy added by the password you can set up ledger live without any password as well.
long story short: your ledger live password doesnt matter, your PINs dont matter too much, but SERIOUSLY, BACKUP YOUR SEED AND PASSPHRASE
I cannot recover, why cant the Ledger makers help me?
unlike in a real life bank which can verify your human identity and issue new keys, to the Consensus network, YOUR KEYS ARE YOUR IDENTITY, and your 24 words are effectively your keys. aside from your backup THERE IS NO BACKUP.
Someone claims to be from [Ledger, the Police, the network of a coin etc.] and wants my 24 words/passphrase to verify something, should I tell them.
I did say your ledger effectively is your debit card, and your 24 words and passphrase are effectively a template for making a new one with full access to your account. and unlike a debit card in real life might have, there are no spending limits aside from the fact you cannot go below zero, and there is no fraud department, or chargeback.
IF ANYONE HAS YOUR KEYS, THEY CAN EMPTY YOUR ACCOUNTS, ALL OF THEM.
An In-Depth Guide to: How do I Fix my Ledger Nano’s Stuck Ethereum Transaction?!?!?! (It’s Been Stuck for Weeks and NOTHING Traditional has Worked!!!!) As Well as: How Do I Choose My Nonce??? I’ve Tried MetaMask, MEW/MyEtherWallet, and Others, but Nothing is Working Correctly!!! I’m Dying by Stress!
So, if you were like me 1-2 months ago, you’ve probably already gone through 2,or 3, ...or 40 articles and guides that probably say something like: “YeP, eVeRy EtHeReUm UsEr WiLl EvEnTuAlLy HaVe ThE LoW-gAs ExPeRiEnCe, YoU’rE nOt AlOnE! DoN’t FrEaK OuT tHoUgH; ThErE iS a WaY tO fIx It!” Chances are, every time you read another useless article, you want to kill the nearest inanimate object, even though it was never alive in the first place. Nonetheless, you’re gonna kill it as much as it can be killed, holding nothing back; or, you’re just plotting to and slowly getting closer to executing the plan (and the object) every time you are insulted once again. However, if you have the ability to download software (MyCryptoWallet) on a PC, it should be safe to relax now. I think you’ve finally found some good news, because I am 99.99...% sure this will work for the issue that so many people are having at this time, around the end of the month of May, year 2020. More and more people are likely to be having this issue soon, since Ethereum's gas prices have been insanely high lately as well as having 300% price changes in a matter of minutes; Etherscan’s Gas tracker is nearly uselessly-inaccurate at this time. I've heard that there's a congestion attack; that was said a week ago, and it appears to be ongoing... (I can't think of any other suspect besides Justin Sun to blame it on... it must be incredibly expensive to overload the blockchain for this long... I may be wrong though...)
Let’s begin For myself, I was trying to send an ERC20 token when this dreadful issue attacked. Specifically, the token was either BSOV or GRT; I sent them 1 after the other and the first succeeded, and the second one took over a week. (They’re both great tokens in my opinion and deserve much more attention than they’ve been getting. BSOV is nearing its 1 year anniversary as I write this, and GRT is still in its 90 day community-development progress test, so of course I'm gonna take this opportunity to "shill" them; they are great tokens with great communities). I was able to finally fix it, after a week of mental agony (also the txn finally processed 1-2 hours before I found the solution, robbing me of the gratitude of fixing it myself... (╯‵□′)╯︵┻━┻ ...but now I guess I can hopefully save some of you the headaches that I endured... ) I’m providing the ability to do the same, in a step by step guide. Why did I go through all of this trouble? I'd fault the fact that I have ADHD and autism, which in my case can multiply each other’s intensity and cause me to “hyper-focus” on things, much much more than most with the same qualities, intentionally or not. Adderall is supposed to give me a bit of control over it, but except for in a very-generalized way, it’s still 90% up to chance and my default-capabilities to allow me control over my attention with self-willpower. But also Karma and Moons pls... ʘ‿ʘ
In MyCrypto, (I'm using the Windows 10 app, version 1.7.10) you will open to a screen that says "How would you like to access your wallet?". Choose Ledger, of course. (Unless your here for some non-ledger issue? Idk why you would be but ok.)
On the next screen (having your nano already plugged in, unlocked, and opened into the Ethereum app) click "Connect to Ledger Wallet"
A screen overlay should appear, titled: "Select an Address". Here is where it may get confusing for some users. Refer to "AAA" below to know how to find your account. (Geez, sorry lol that was a huge amount of info for a reddit reply; I might've over-elaborated a little bit too much. but hey it's valuable information nonetheless!)
After escaping the "AAA" section, you'll have accessed your account with MyCrypto. Awesome! To find your ERC20 tokens, (slight evil-laughter is heard from an unidentifiable origin somewhere in the back of your mind) go to "AAB".
(You may have decided to find the token(s) on your own, rather than daring to submit to my help again; if so, you may pity those who chose the other path... ~~(￣▽￣)~~) Now, once you've added your token, you should revert your attention to the account's transfer fill-out form!
I'll combine the steps you probably understood on your own, already. Put in the address that your stuck transaction is still trying to send currency to. If an ERC20 token is involved, use the drop-down menu to change "ETH" to the token in trouble. Input your amount into the box labeled... wait for it... "Amount". Click on "+Advanced".
Refer to Etherscan.com for the data you will need. Find the page for your "transaction(txn) hash/address" from the transaction history on the wallet/Ethereum-manager you used to send from. If that is unavailable, put your public address that your txn was sent from into the search tool and go to its info page; you should be able to find the pending txn there. Look to open the "more details" option to find the transaction's "Nonce" number.
Put the nonce in the "Nonce" box on MyCrypto; you will contest the pending txn with a new txn that offers larger gas fees, by using the same nonce. If (but most likely "When") the new transaction is processed first, for being more miner-beneficial, the nonce will then be completed, and the old transaction will be dropped because it requests an invalid, now-outdated nonce. Your account will soon be usable!
Go to the Gas Tracker, and it may or may not provide an informative reading. Choose whatever amount you think is best, but choose wisely; if you're too stingy it may get stuck again, and you'd need to pay another txn's gas to attempt another txn-fix.
At the time I write this, I'd recommend 50-100 gwei; to repeat myself, gas requirements are insane right now. To be safe, make the gas limit a little higher than MCW's automatic calculation, you may need to undo the check-mark for "Automatically Calculate Gas Limit".
Press "Send Transaction"!!!
You will need to validate the action through your nano. It will have you validate three different things if you are moving an ERC20 Token. It's a good idea to verify accuracy, as always.
Well, I hope this worked for you! If not, you can let me know in a reply and I'll try to figure it out with you. I like making these in-depth educational posts, so if you appreciate it please let me know; I'll probably make more posts like this in the future! ( Surely this is at least far better than Ledger's "Support" article where they basically just tell you "Yeah, we haven't bothered to make a way to manually select nonces. I guess we might try to make that available for Bitcoin accounts at some point in the future; who knows? lol"... that's not infuriating at all, right?)
AAA: Before I tell you how to find your address, I will first make it clear, within the italicized text, exactly which address you are looking for, if you are not already sure: You may also skip the text written in italics if your issue does not include an ERC20 token, if you wish. Ledger Live can confuse some users with its interface. On LL, to manage an ERC20 token, you first must go to your Ethereum account and add the token. When you then click on the added token under "Tokens" below the graph chart for your account's ETH amount over time, the screen will then open a new screen, that looks just the same, except focused on the specific ERC20 token. To confuse users further, there is then an option to "Star account", which then add the ETH icon with the ERC20 token's first letter or symbol overlapping, onto the easy access sidebar, as if it was another account of similar independency to the ETH account it was added to. This improperly displays the two "accounts" relation to each other. Your ERC20 holdings (at least for any and all ERC20 that I know of) are "held" in the exact-same address as the Ethereum address it was added to, which also "holds" any Ether you've added to it. You send both Ether (ETH) and any ERC20 Tokens to and from only Ethereum addresses of equivalent capabilities, in both qualities and quantities. In all basic terms and uses, they are the same. So, to know what the problematic account's address is, find the address of the Ethereum account it was added to in Ledger Live. Now, to find your address on MyCrypto, the most reliable way to find it, that I am aware of, is this: Open Ledger Live. Go to the screen of your Ethereum address (again, this is the one that you added your ERC20 token, if applicable. If you're not dealing with an ERC20 token, you may ignore everything I've put in Italics). Click on "Edit account"; this is the icon next to the star that may look like a hex-wrench tool. On the new screen-overlay, you will see "> ADVANCED LOGS". Click on the ">" and it will point down while revealing a drop-down with some data that you may or may not recognize/understand. Likely to be found indented and in the middle-ish area, you will see this line, or something hopefully similar: "freshAddressPath": "44'/60'/X'/0/0", The "X" will probably be the only thing that changes, and the actual data will have a number in its place; it will not be a letter. Let's now put that line to use in MyCrypto: Take the 44'/60'/X'/0/0 , and make sure you DO NOT copy the quotation marks, or that comma at the end either. You can do this before or after copying and/or pasting, but drop the second "/0" at the end; it was not necessary in my case, I expect that you won't need it either, and will probably just make MyCrypto see it as an invalid input. Okay, now go back to the "Select an Address" screen-overlay in MyCrypto. Next to "Addresses", click on the box on the right, and you should be shown a list of options to select from in a drop-down menu. Scroll all the way down, and you should find the "Custom" option at the very bottom. Select it. A new box will appear; probably directly to the right of the now-shortened box that now displays the "Custom" option that you just selected. This box will offer an interface for typed input. ...yep... once again, believe it or not, you should click it. Type " m/ ", no spaces before or after. Type in or paste the data we retrieved from ledger live. The box should now hold this: m/44'/60'/X'/0 Again, X should be a number. In fact, that number is probably equal to the number of Ethereum (not including any ERC20 wannabe) accounts that you've made on Ledger Live before making the one we're working on right now! (1st Eth. Acc. would have: X = 0, 2nd: X = 1, 3rd: X = 2, ...) Make sure you've included every apostrophe ( ' ), and solidus ( / ); there is NO APOSTROPHE for the "m" at the start and the "/0" at the end! If you press the enter key or click on the check-mark to the right of where you typed, the appropriate addresses will be generated, and the address you created through Ledger Live should be the first one on the list! Select your address and press "Unlock", and you are now accessing your account through the MyCrypto app's interface!
AAB: In order to access your ERC20 token, you will need to add them first. You may have to scroll down, but on the right-side of your unlocked account screen, you'll see a box with "Token Balances" as its header. Click "Scan for tokens". This may take a short bit of time, and when it's done it may or may not display your ERC20 token. If it worked, you can head on back to the main part. If you got the result I did, it won't display your token, or, if our result was exactly the same, it won't display any at all. However, you should now have the "Add Custom Token" option available, so see where that takes you. You should discover four boxes, specified in order (Address/ Decimals / Token_Symbol / Balance). You may only need to fill in the "Address" box, but if you need to fill others, you'll find those with the token's address; here's 2 ways to find it, if you don't already know. Method I: Since you've probably already been managing your token with Ledger Live, you can go to the LL screen of your "account" for that token; Right next to the account's icon, and directly above the name, you'll see: Contract: 0x??????...???????? Yes, go on; click it. You'll find the token's page on Etherscan; this was just a shortcut to the same place that both of the two previously referenced methods lead to. Skip to method... III? Method II: Go toEtherscan.com, or a similar Ethereum-blockchain-monitoring website, if you have a different preference. Search for the name of your token, and you should be able to see it as a search result. Activate your search manually of by selecting search option. Continue on with Method III. Method III (I&II; what makes you think there was a third method? I said 2!): At this point, you should find the "contract address" somewhere on the screen. This is the identity of the creature that breathes life into the token, allowing it to exist within the world of Ethereum. Steal it, and tell MyCrypto that you've left some of "your" tokens in the address of your ledger's Ethereum account. MyCrypto will trust and believe you without any concern or doubt, just by putting "your" contract address in the box for "Address"; it's almost too easy! Well whaddya know, this one isn't actually too long! Don't tell anyone who may have taken a little longer whilst finding out how to do it themselves, though. There's value in trying to do something on your own, at least at first, so I'll let them think they made the right choice (¬‿¬). But take this star for humbling yourself enough to seek further help when you need it, since that is a very important life skill as well! (o゜▽゜)o☆ Now, back to the useful stuff at the top...
EDIT: A comment below made me realize that this info should be added too. Here is my reply to the comment saying I could just use MetaMask. I said in the title that this guide is for questions where MEW and MetaMask aren’t working, but I guess it’s easy to miss. I used my u/caddark account to respond: (Using this account because u/caddarkcrypto doesn’t meet the karma/age standards to comment; the post had to be manually approved.) I guess I didn’t make it entirely clear; sorry: The target audience for this guide is anyone with a stuck Ethereum transaction that was initiated through Ledger Live AND are experiencing the same difficulties I had encountered while trying to fix this issue for myself. This wasn’t any regular stuck Ethereum transaction. Apparently before, there was an issue that made a Ledger Nano nearly impossible to connect to MetaMask (which is also Brave Browser’s integrated “crypto wallet” for the desktop version) and/or MEW (also perhaps any other browser wallets made for chrome and/or brave) that I heard was supposed to be fixed in a recent update. It might’ve been mostly patched, idk, but during my experience, (in which I was using the latest version of Ledger Live that is available right now,) that issue still remained. The really weird part was that it successfully connected to the browser wallets again after I fixed the stuck transaction. At first I thought that somehow the txn was what was bugging the connection. However, later, during no txn issues, I was again unable to connect. Seeing the same connection error again later, I opened up the MCW app I downloaded the day before, and was going to just use that. While in the process of operating MCW, I suddenly had another idea to try for the browser wallet so I went back to that just to quickly test it. The browser wallet worked perfectly... I don’t know how, but I think that somehow, something in MCW’s software, makes the browser wallets work. They don’t work for me without having MCW opened in the background first. EDIT 2: Markdown decided to stop working after I did the first edit... I might fix it tomorrow... how did that happen though??? What did I do? EDIT 3: nvm, I'm just fixing it now; I won't get much sleep tonight I guess.

Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it. Filecoin announced, that there will be more delays before its main network is officially launched. Filecoin developers postponed the release date of their main network to late July to late August 2020. As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process. Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market. Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors. The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020. They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit. The Filecoin team noted the following: “We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks. Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet. The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020. The updates to the project can be found on the Filecoin Road Map. Filecoin developers stated: “This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage. Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain. In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards. Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21. Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price. Mining in Filecoin In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency. Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data. Filecoin will contain several types of miners: Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out. Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power. Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network. The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into. In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.
The current system specifications recommended for running the miner are:
NVIDIA-manufactured GPU (to be expanded).
SSD drive designated as large buffer (512GB +).
Large amount of RAM for data replication account (128GB +)
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars. Proceed to mining Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract. Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually. After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started. Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page. At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention. Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt. Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network. Duration of operation, cutting and penalties “Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network. In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error. Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily. An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection. The sector will pay an error fee after the penalty of the sector once the error is discovered. Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network. Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function. Filecoin miners Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.” With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices. Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless. Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers. Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network. However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners. These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB). Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development. “Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital. “Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said. Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT. In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive. To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day. As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force. The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million. This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs. After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020. The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process? Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance. In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners: The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue. It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown. It seeks to promote mining using Filecoin Discover Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day. Ian Darrow, Head of Operations at Filecoin, commented on the announcement: “Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”. Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more. Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds. In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations. The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested. “The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”. IPFS and Filecoin Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure. IPFS It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live. The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides. Using IPFS In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data. Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service. Using Filecoin The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone. Filecoin, powered by IPFS It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS. Some advantages of sharing Filecoin with IPFS:
Filecoin and IPFS CIDs share hash specifications.
Use libp2p by Filecoin nodes to create secure connections with each other.
Messaging between nodes and cluster propagation is facilitated in Filecoin by libp2p pubsub.
IPLD use for blockchain data structures.
Use Graphsync to transfer data between nodes.
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol. Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated. PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage. In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected. Resources :
Bull market is back… Another wave of hacker attacks starts again?
The picture from COINDESK related reports On Aug. 2, Ethereum Classic Labs (ETC Labs) made an important announcement on ETC blockchain. ETC Labs said due to network attack, Ethereum Classic suffered a reorganization on August 1st. This has been the second attack on the Ethereum Classic Network this year. Did renting-power cause the problem again? In this ETC incident, one of the miners mined a large number of blocks offline. When the miner went online, due to its high computing power, and some versions of mining software did not support large-scale blockchain mergers, the consensus failed. Therefore, the entire network was out of sync, which produced an effect similar to a 51% attack. Finally, it caused the reorganization of 3693 blocks, starting at 10904147. The deposit and withdrawal between the exchanges and mining pools had to be suspended for troubleshooting during this period. Media report shows that the blockchain reorganization may be caused by a miner (or a mining pool) disconnected during mining. Although it has been restored to normal after 15 hours of repair, it does reflect the vulnerability of the Proof of Work (PoW) network: once the computing power of the network is insufficient, the performance of one single mining pool can affect the entire network, which is neither distributed nor secure for the blockchain. Neither does it have efficiency. At present, most consensus algorithms of blockchains are using PoW, which has been adopted over 10 years. In PoW, each miner solves a hashing problem. The probability to solve the problem successfully is proportional to the ratio of the miner’s hash power to the total hash power of mainnet. Although PoW has been running for a long time, the attack model against PoW is very straightforward to understand, and has attracted people’s attention for a long time: such an attack, also known as double-spending attack, may happen when an attacker possesses 51% of the overall network hash power. The attacker can roll back any blocks in the blockchain by creating a longer and more difficult chain and as a result, modify the transaction information. Since hash power can be rented to launch attacks, some top 30 projects have suffered from such attacks. In addition to this interference, the main attack method is through the computing power market such as Nice Hash. Hackers can rent hashpower to facilitate their attacks, which allows the computing power to rise rapidly in a short time and rewrite information. In January of this year, the Ethereum Classic was attacked once, and it was also the case that hackers can migrate computing power from the fiercely competitive Bitcoin and Ethereum, and use it to attack smaller projects, such as ETH Classic. The picture shows the cost of attacking ETH Classic. It can be seen that it costs only $6,634 to attack ETH Classic for one hour. The security of one network is no longer limited by whether miners within the main net take more than 51% of the total hash power, rather it is determined by whether the benevolent (non-hackers) miners take more than 51% of the total hash power from the pool of projects that use similar consensus algorithm. For example, the hash power of Ethereum is 176 TH/s and that of Ethereum Classic is 9 TH/s. In this way, if one diverts some hash power from Ethereum (176 TH/s) to Ethereum Classic, then one can easily launch a double-spending attack to Ethereum Classic. The hash power ratio for this attack between the two projects is 9/176 = 5.2%, which is a tiny number. https://preview.redd.it/qj57vgmgb9f51.png?width=699&format=png&auto=webp&s=39c1efc3645f268dbf1c73e1b373d532d5461006 As one of the top 30 blockchain projects, Ethereum Classic has been attacked several times. Therefore, those small and medium-sized projects with low hash power and up-and-coming future projects are facing great potential risks. This is the reason that many emerging public chain projects abandon PoW and adopt PoS. Proof of Stake (PoS) can prevent 51% attack but has problems of its own In addition to PoW consensus, another well-adopted consensus algorithm is Proof of Stake (PoS). The fundamental concept is that the one who holds more tokens has the right to create the blocks. This is similar to shareholders in the stock market. The token holders also have the opportunities to get rewards. The advantages of PoS are: (i) the algorithm avoids wasting energy like that in PoW calculation; and (ii) its design determines that the PoS will not be subjected to 51% hash power attack since the algorithm requires the miner to possess tokens in order to modify the ledger. In this way, 51% attack becomes costly and meaningless. https://preview.redd.it/rf65o1vhb9f51.png?width=685&format=png&auto=webp&s=9d7a9f9dab6ce823a224e91afa9d116310cf27e1 In terms of disadvantages, nodes face the problem of accessibility. PoS requires a permission to enter the network and nodes cannot enter and exit freely and thus lacks openness. It can easily be forked. In the long run, the algorithm is short of decentralization, and leads to the Matthew effect of accumulated advantages whereby miners with more tokens will receive more rewards and perpetuate the cycle. More importantly, the current PoS consensus has not been verified for long-term reliability. Whether it can be as stable as the PoW system is yet to be verified. For some of the PoW public chains that are already launched, if they want to switch consensus, they need to do hard fork, which divides communities and carries out a long consensus upgrade and through which Ethereum is undergoing. Is there a safer and better solution? QuarkChain Provide THE Solution: High TPS Protection + PoSW Consensus For new-born projects, and some small or medium-sized projects, they all are facing the problem of power attack. For PoW-based chains, there are always some chains with lower hash power than others (ETC vs. ETH, BCH vs BTC), and thus the risk of attack is increased. In addition, the interoperability among the chains, such as cross-chain operation, is also a problem. In response, QuarkChain has designed a series of mechanisms to solve this problem. This can be summed up as a two-layer structure with a calculation power allocation and Proof of Staked Work (PoSW) consensus. First of all, there is a layer of sharding, which can be considered as some parallel chains. Each sharding chain handles the transactions relatively independently. Such design forms the basis to ensure the performance of the entire system. To avoid security issues caused by the dilution of the hash power, we also have a root chain. The blocks of the root chain do not contain transactions, but are responsible for verifying the transactions of each shard. Relying on the hash power distribution algorithm, the hash power of the root chain will always account for 51% of the net. Each shard, on the other hand, packages their transactions according to their own consensus and transaction models. Moreover, QuarkChain relies on flexibility that allows each shard to have different consensus and transaction models. Someone who wants to launch a double-spending attack on a shard that is already contained in the root chain must attack the block on the root chain, which requires calling the 51% hash power of the root chain. That is, if there are vertical field projects that open new shards on QuarkChain, even with insufficient hash power, an attacker must first attack the root chain if he or she wants to attack a new shard. The root chain has maintained more than 51% of the network’s hash power, which makes the attack very difficult. https://preview.redd.it/rxpohs7jb9f51.png?width=674&format=png&auto=webp&s=e2df1307a1753542472f2b6da88e7a4022b30884 As illustrated in the diagram, if the attacker wants to attack the QuarkChain network, one would need to attack the shard and the root chain simultaneously. PoW has achieved a high level of decentralization and has been verified for its stability for a long time. Combining PoW with the staking capability for PoS would make use of the advantages of both consensus mechanisms. That is what QuarkChain’s PoSW achieves exactly. PoSW, which is Proof of Staked Work, is exclusively developed by QuarkChain and runs on shards. PoSW allows miners to enjoy the benefits of lower mining difficulty by staking original tokens (currently it’s 20 times lower). Conversely, if someone malicious with a high hash power and does not stake tokens on QuarkChain, he will be punishable by receiving 20 times the difficulty of the hash power, which increases the cost of attack. If the attacker stakes tokens in order to reduce the cost of attack, he/she needs to stake the corresponding amount of tokens, which may cost even more. Thus, the whole network is more secure. Taking Ethereum Classics (ETC) as an example, if ETC uses the PoSW consensus, if there was another double-spending attack similar to the one in January, the attacker will need at least 110Th/s hash power or 650320 ETC (worth $3.2 million, and 8 TH/s hash power) to create this attack, which is far greater than the cost of the current attack on the network (8Th/s hash power) and revenue (219500 ETC). Relying on multiple sets of security mechanisms, QuarkChain ensures its own security, while providing security for new shards and small and medium-sized projects. Its high level of flexibility also allows the projects to support different types of ledger models, transaction models, virtual machines, and token economics. Such great degrees of security and flexibility will facilitate the blockchain ecosystem to accelerate growth of innovative blockchain applications.

Bitcoin at $ 288,000? BTC price shows bullish signal like 2016
Bitcoin's price development has been relatively stable in recent weeks. The cryptocurrency has been trading in the $ 9,200 range since early June, which is the price at the time of publication. However, Bitcoin is currently showing signals that could indicate an upcoming bull market. According to a report by the Kraken Stock Exchange, Bitcoin is only a 10% jump away from entering a massive upward trend. As Kraken describes, to enter a bull market, Bitcoin must break the key resistance at $ 10,500, as shown below. https://preview.redd.it/0d4bm64zsla51.png?width=1276&format=png&auto=webp&s=b3a670c135792f34af6714fc8ab9d48cef7dc77e With that in mind, the report says Bitcoin could soon break resistance or take the risk of testing support at $ 6,000 to $ 7,000. This would end a period that some analysts have described as very stable. In fact, this is similar to the price development in 2016 and 2017, when Bitcoin initially tended to move sideways for a very long time and finally reached its all-time high of USD 20,000 in late 2017. According to analyst Moon Capital, the Bitcoin hash ribbons have crossed, revealing a massive buy signal that has historically pushed Bitcoin's price up. The signal was also there before the 2017 Bull Run. Therefore, the analyst predicts that BTC will rise to $ 288,000. The "hash ribbons" indicator is based on the hash rate of the Bitcoin network. It is calculated by comparing the short-term moving average and the long-term moving average of the Bitcoin hash rate. As soon as these two cross, a bullish indicator is generated. A breakdown is considered bearish. Capriole's digital asset manager, Charles Edwards, also noted the formation of this indicator. However, Edwards recommended waiting until midnight today (July 12th UTC) for the crossing of the hash ribbons to be confirmed. He also said the BTC price for confirmation should close above $ 9,230.
Bitcoin fundamentals support upcoming uptrend
On the other hand, Bitcoin's fundamentals seem to support a bull market. Bitcoin's hash rate has increased significantly since the difficulty adjustment in June. According to blockchain.com, the hash rate of Bitcoin reached a new high of 125.99 terra hashes per second (TH / s) on July 7. In this context, analyst and inventor of Bitcoin's stock-to-flow model, Plan B, said Bitcoin has weathered the worst of the past few months. In addition, he stressed that the cryptocurrency will soon peak at its hash rate, confirming the good health of the Bitcoin network.
So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this. You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".
Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be: 116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus" So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.
Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block. Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
d - The delta above majority. So at 51%, d=1%
n - The length of reorg that the minority pool could attempt
t - The pre-attack blocktime based on hashrate (assume 10 min)
M (aka Mp) - The percent of hashpower held by minority (49%)
S (aka Sp) - The percent of hashpower held by Spectre (51%)
m (aka Mt) - The blocktime durring attack on the minority chain
s (aka St) - The blocktime durring attack on the Spectre chain
n*m = s*(n+1) - Break even, when minority mines n at the same rate Spectre mines n+1
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p) This will produce the following equations for the values we are interested in. m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define Plugging the equations into excel produces the following (assuming t=10)
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51% So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52% Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left. Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack. Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network. Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Levrg / Block
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total. 1 - All "hashes" are hashes per second 2 - TH = 1012 or 10004 hashes per second 3 - EH = 1018 or 10006 hashes per second 4 - Assume a market rate of 0.101 USD / TH / day 5 - Assume an average daily network hashrate of 116.73 EH
TH = 1012 = 10004 hashes_per_second EH = 1018 = 10006 hashes_per_second 21.113 0.101 daily USD per TH/s 116.73 EH/s So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this. You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".
Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be: 116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus" So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threahold they could scale back on the "marketing" and thus reduce their daily burn.
Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce an n+1 blocks and compare that to how long (statisticly) with take Bond to produce another block. Although this can be hammered out iterive calculations, a better approach will be an algebraic solution. Lets walk through the equations:
d - The delta above majority. So at 51%, d=1%
n - The number of blocks the majority can reorg
t - The pre-reorg blocktime based on hashrate (10 min)
M (aka Mp) - The percent of hashpower held by minority (49%)
S (aka Mp) - The percent of hashpower held by Spectre (51%)
m (aka Mp) - The blocktime durring attack on the minority chain
s (aka Mp) - The blocktime durring attack on the Spectre chain
n*m = s*(n+1) - Break even, when minority mines n at the same rate Spectre mines n+1
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p) This will produce the following equations for the values we are interested in. m(t,d): t*(1/2-d) # from `m` define s(t,d): t*(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define Here's a table
solve(nm = s(n+1), d) n = s/(m-s) b = m*M/p ``` Tb = The avg time between blocks won by Bond durring the reorg Ts = The avg time for Spectre to produce a block durring the reorg Tm = The avg time for the main chain to produce a block durring the reorg n = The number of blocks Specter will need to reorg Tb = 10_min / 49% / 3% = 10.89 Hrs Ts = 10_min / 51% = 19.61 Min Tm = 10_min / 49% = 20.41 Min Solve for the amount of blocks Specter can reorg Tmn > Ts(n+1) Tnn > Tsn + Ts n > Ts/(Tn - Ts) n > 24.5 Therefore: Spectre can produce 26 blocks faster than the main chain can produce 25. Specter has to win the reorg before Bond produces another block Assert: Ts * (n+1) < Tb 19.61_min * 26 < 10.89_hrs 8.50_hrs < 10.89_hrs ``` So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 10.89 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52% Doing the same math again, with 52% Spectre can ice out any pool who has up to 7% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 16% of his competitors. This can cascade on and on until Spectre is the only public pool left. 1 - All "hashes" are hashes per second 2 - TH = 1012 or 10004 hashes per second 3 - EH = 1018 or 10006 hashes per second 4 - Assume a market rate of 0.101 USD / TH / day 5 - Assume an average daily network hashrate of 116.73 EH ``` solve(nm = s(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(nm = s(n+1), d) n = s/(m-s) b = mM/p solve(b = s(n+1),p) m(t,d): t(1/2-d) # from m define s(t,d): t(1/2-d) # from s define n(s,m): s/(m-s) # from n solve d(n): 1/(4n+2) # from d solve p(d): 2d # from p solve b(t,p): t/p # from b define ```
[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.
Electricity consumed by bitcoin network has been constantly and noticeably increasing. During the past years the consumption reached such big a scale, that it can be compared to electricity consumption of some countries, according to BlockchainAnalytics.pro research. The world’s first cryptocurrency is steadily becoming more popular and expensive every year. This motivates more individuals and companies to enter the mining business to earn a bitcoin share.
More miners, more efficient equipment
To validate a block of transactions and receive a reward, miners compete with each other by solving a deliberately complicated mathematical task, or puzzle. Those miners who own more computing power (hashrate) have more chances to win the competition. This incentivizes miners to buy more powerful equipment that consumes more electricity. At the same time, mining equipment efficiency is constantly improving, and with time less electricity is required to produce the same hashrate. This factor allows to slow down the increasing demand for electricity. For example, in 2016 Bitmain, world’s largest manufacturer of mining equipment, launched the legendary Antminer S9, which consumed 100 watts to produce one terahash per second, or 100 W/TH/s. The best modification of Antminer S15, released in 2018, consumed 57 W/TH/s. Currently, the most efficient Antminer S17 consumes only 40 W/TH/s. https://preview.redd.it/gh343l3p09j41.png?width=930&format=png&auto=webp&s=e350c1e7832e37c1e3c3aeac974428cca7f0f874 It is assumed that the market competition compels manufacturers to keep up with each other in developing more efficient hardware. If some manufacturer brings next-generation chips to market, other manufacturers start to produce chips with the same characteristics at about the same time. On the other hand, new miners are joining the network, thus increasing the hashrate. So the demand for electricity continues to grow. Also, it can be noticed later that the electricity consumption chart is similar to that of hashrate chart. https://preview.redd.it/3k32ci6q09j41.png?width=930&format=png&auto=webp&s=e70f600419bcbc9e7e82506b5f12bf4da6f00584
The incremental volume of electricity consumption is calculated by multiplying newly added hashrate by the best mining efficiency available at that moment. The sum of incremental volumes represents cumulative amount of electricity consumed by bitcoin network. The metric is expressed in terawatt-hours (TWh). To get annualized volume in terawatt-hours we multiply the consumption by 24 hours and 365 days. A 100-day moving average was applied to hashrate to make the final result less dependent on the short-term hashrate fluctuations. Assumptions, used in this study, are very conservative. It means that the results are in the lower limit of the range of possible volumes, and the actual electricity consumption can be higher. A detailed explanation and interactive charts are provided here: https://www.blockchainanalytics.pro/btc/electricity-consumption/ https://preview.redd.it/jol3703r09j41.png?width=929&format=png&auto=webp&s=252d4d67ff6882bb32ad63238537a41305719f05
Currently, annualized electricity consumption in bitcoin network is 57 TWh. To help readers get an idea of how much electricity the bitcoin network consumes, a comparison with some countries is provided alongside. Portugal consumes 49 TWh per year, Romania – 50 TWh, Czech Republic – 59 TWh. Some more numbers for comparison:
05-05 19:14 - 'An Island Nation with Bitcoin as the currency' (self.Bitcoin) by /u/Decamerch removed from /r/Bitcoin within 72-82min
''' Hello all, I am here with my plan for my [subreddit]1 Reddit Nation If you are interested in joining a (hopefully) newly formed island nation then this is the place to be. I have prepared a plan that explains how we will go about doing such a task. More detailed elaborations for each component of the plan will be given at request. Obviously the first question is where we would have our island. I have identified places of interest. One place of interest is the Nation of Belize. Belize is a small nation with a low GDP of 2 Billion and they are selling off most of their island. Islands with 50-100 acres can be acquired for around 500,000; give or take 50,000. From the people (Government Officials) I have contacted, they are perfectly okay with this plan. Now here is a 5 step proposal of how this will come to fruition (I will expand on how we will finance this)
Acquire the island
Set up the initial infrastructure
Form of Government that I propose is a constitutional monarchy
Country will be run as a democracy (two chamber form of parliament)
Noble titles such as Duke, Earl, Count, Lord, Baron etc will be sold off to help initially finance the island.
Establishment of the Government Building
For now this is where the government will convene until more infrastructure is added and the island is improved.
People will be made citizens at this location
Establishment of Civil Services
Waste collection, Police, Social Services
Establishment of a Port
This will allow supplies to enter the island.
This will allow for the island to participate with the rest of the world economically(I will expand on this later).
The port will function as the entrance point and exit until the runway can be constructed.
Establishment of Resident Housing
This temporary housing will be until the island can be developed and more permanent buildings can be put up.
Resident Housing and the Government building will be set up near the port until island development is completed
Set up a massive solar powered crypto mining operation to help finance further development of the island
A partnership with big mining companies can be brokered to have this set up
Make the Island a desirable location
Set up the island as a luxury city
Free housing for citizens
Free healthcare for citizens
Free schooling and university for citizens
Build resorts and legalize gambling on the island
The revenue generated from such activities will help finance further development of the island
With the revenue generated from this, the island will be able to provide for the residents a luxury city
The gambling industry investments will help to finance the island as well
Make the island a banking haven
Set up a bank on the island
No KYC laws will be enforced on the island
This will attract forgien investment into the island
Allow cryptocurrency companies to conduct business without oversight and for miners to set up large scale operations using solar powered energy
No income tax,sales tax, capital gains tax or corporate on the island
Commercial businesses such as casinos, resorts, and banks will just pay slightly inflated property taxes
This will help attract a lot more forgien investment as well
Will attract companies to set up offices here and thus bring jobs to the island.
Expand on the island infrastructure
Build an airport. The islands have enough space to accommodate runways for planes even up to jumbo jets
Build more free luxury housing for residents
Establish schools and universities
Establish a healthcare system
Enjoy the luxury haven of an Island that we have built
Now for the question of how much this island will cost and how we will get the funding According to my calculations (you can look at them below) it will cost us $2,600,000
The Island itself
200,000 to build
This will benefit us later when we receive forgien investments
500,000 for 250 passenger ferry
We will budget around 100,000 for operating costs
These buildings will be permanently built but occupied until the island is built and then will be sold off to recoup the investment.
Around 50,000 to purchase initial equipment and medical supplies
Another 100,000 to purchase ATVs
Another 100,000 to purchase off roading vehicles
Bitcoin mining operation
We will get the money for the operation by partnering with a large company
We will purchase MRE’s and other preserved food products for the island
An exact count of this cannot be made until we move further into the plan
Further development of the island
This will be financed by the forgien investments in regards to banking, gambling and tourism along with money raised from property taxes
Now in regards to how we will raise that sum
We will sell off noble titles (this is why we will set up a constitutional monarchy)
While no price has been established yet, the titles for sale can include
A small percentage of the island (less than 25%) will be earmarked for sale immediately. The part earmarked for sale will be part of the planned downtown district/capital and developers of this land will be allowed to build whatever structures they want and won't have the problem of jumping through hoops like zoning laws.
On a 60 acre island, 15 acres would be marked for sale
The acres on this haven of an island will be sold for 250,000 each so the island would raise 4.5 million and the sale of said acres will help kickstart the massive infrastructure of the island and provide the island with adequate funding.
Once the island is set up, the island will continue to profit from digital activities which will allow it to not have to charge an income tax or corporate tax
Digital activities include the solar powered bitcoin mining operation
We will partner with an existing bitcoin company for this
Solar powered web hosting
People can become citizens for a fee of $10 which will mainly go to the printing of their ID and filing in the government archives but the island will profit a few dollars off of this
Hi all, new to cloud mining and researching at the moment. I was wondering whether anybody could share their experiences and things to consider regarding 'reinvesting' vs. profit taking. As I understand, retaining the same hash rate as the difficulty adjustment increases reduces your reward. Reinvesting your reward into greater hash power will merely keep you treading water in terms of your reward rate, and eat into your take home profits. Surely there comes a point where you decide to stop reinvesting and take the profit instead? Or am I correct in thinking that people reinvest to retain their hash power, with the expectation that the coin will be worth considerably more in the future and the profit can be taken by cancelling the reinvest option further down the line where the profits will be greater? Is my above logic correct? What other considerations are there? Are there reinvesting strategies that people use? Thanks in advance.
[ 🎶 Thinking Cap ] This post is framed around results of cypher-based queries for the number 1234 against my custom lexicon files built up over a year of phrase inputs (mostly gleaned from newspaper headlines and their 'quoted phrases', or stream of conciousness inspired by them). There are not very many, but the few there are appear to be instructive. I have used some repetition to aid those with trouble remembering numbers. Perhaps NSFW. (For the confused: see here, here and here) If you are brand new to this collection of scrolls, I recommend reading (as much as you can of) this before returning here, which will help to justify my particular focus below (the belt). Did you gnow A=1? There are 26 letters in the English-Latin Alphabet. The basic alphabetic gematria code acknowledges that A=1, B=2, C=3, ..., Z=26 (ie. ordinal gematria). In this basic alphabetic cypher (which is implied if I do not specify):
"Alphabetic Codes" = 123
... "Reveal The Code" = 123
... .. .. "To Reveal All" = 123
If you flip the numeric ordering about (ie. look in the mirror: treat 'Z' as 1, down to 'A' as 26), then...
This ("The ABC") is the name of the earliest alphabet primer textbooks for kids.
The first church primers paralleled the introduction of school textbooks known as “the ABC”
The Alphabet is a vessel for messages:
"Boat" = 123 primes (ie. an Ark ... an Archive ... built using a geometric Architecture of symbols)
If, instead of the basic alphabetic ordinal cyphers above, we use another cypher some call Agrippa's Key, and some call the 'jewish cipher', which is based on the ancient Hebrew and Greek gematria charts, and maps that scheme to the Latin Alphabet, we can ask a catch-phrase question (written more formally than usual)
What's in a name?
"What is in a name?" = 1234 jewish-latin-agrippa
Here we move beyond the three steps of ABC and arrive at the Door of Dalet. Behind it, if we have the write keys, we might discover...
ie. quantum-entanglement: you cannot give birth to your first alphabetic Son, a strong boy named Aleph, and deny he is '1'. You cannot have your second child, a beautiful maiden, Beth, and deny she is '2'. Animals on the ark 2 by 2. You cannot order the alphabet, and deny the letters have ordinal indexes (ie. numbers associated with them - significant others)
Obstetrics is the field of study concentrated on pregnancy, childbirth, and the postpartum period. As a medical specialty, obstetrics is combined with gynaecology under the discipline known as obstetrics and gynecology (OB/GYN) which is a surgical field.
... ( "The Last Proof of Life After Death" = 911 primes )
I have a spell-matching feature that can cross-match multiple cypher results and return the 'closest frequency matches' of all the spells I've ever entered into my gematria tools. At the time of writing the lexicon file is half a megabyte in size (plain text) and contains 37,694 words and phrases. When I ask for the spellings that most closely match: "live forever", I get the following three results as top matches:
'white liquid', 'into the girl', and 'the dilution' (with 8+ cypher matches)
There are a lot of flowery symbolic or metaphorical phrases that it could have returned, but it seems the Heptapods are rather blunt. Again:
"Divine Feminine" = 911 jewish-latin-agrippa
... .. "Sexy Girl" = 911 jewish-latin-agrippa
From... Revelation 9:11 King James Version (KJV):
And they had a king  over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon  , but in the Greek tongue hath his name Apollyon.
This is perhaps a dual - the Abaddon is both Father Beast (and Lord of the Harem, perhaps, given the plural 'them') and the Beastly Progeny (ie. King and Prince):
"Pregnant" = 333 jewish-latin-agrippa
"The Temple" = 333 jewish-latin-agrippa
... "A Baby" = 333 trigonal
The angelic little baby, retrieved from the bottomless pit, is the apple of mommy and daddy's eyes (even though it is very naughty, ruling over their lives for many years after his or her noxious retrieval from the Underworld).
Viva Las Vegas (ie. V.L.V ): 777 (ie. to win at slots):
"A Triple-Seven" = 1234 trigonal | 2,322 squares
The Boeing 777 is a premiere passenger aircraft. The Boeing 787 is called the Dreamliner (ie "The Call" = 787 squares ... of Morpheus) The Boeing 747 is Old Faithful, the Jumbo Jet of Time Air Force One is a 747
"Air Force" = 223 primes
"Winds" = 223 primes
"Goddess" = 223 primes
... "The Law" = 223 primes
... "Air Force" = 223 primes
"Winds" = 223 primes
"The Law" = "Goddess" = 223 primes
She steps on "The Scale" = 223 primes ... ...and hopes she is ...
"Weightless" = 1234 jewish-latin-agrippa
From an old Alphabet Primer:
... He that ne'er learns his ABC, ... For ever will a Blockhead be. ... But he that learns these Letters fair, ... Shall have a Coach to take the Air.
Enregisterment is often partially, rather than completely, true, sort of like an accent viewed through a funhouse mirror.
I was triggered to made this post due to various recent media 'events', this 'crazy' 'news item' the final straw that broke the gimel's black (I link to old reddit theme because it is objectively better ):
These are things we can imagine Alphabet Sages might desire to encode and honour - as much for a mnemonic purpose, as for teaching purposes, or for archiving [...] knowledge [...] or purely for the sake of esoterica itself (ie. wizard just likes math, or architecture, and thus honours math and arches, secretely in words using basic algebra and references to certain idioms and golden numbers. Wizard works for King, shows him tricks. King decrees new Bible edition, and new Dictionary version).
He found me to be of a tractable, inquiring, and fearless disposition. A dash of melancholy is lacking in me, else I would make all, who are inclined to blame the Comte de GABALIS for having concealed nothing from me, confess that I was a not unfit subject for the Occult Sciences. One cannot make great progress in them, it is true, without melancholy; but the little that I possess in no wise disheartened him. You have, he told me a hundred times, Saturn in an angle, in his own house, and retrograde; some day you cannot. fail to be as melancholy as a Sage ought to be; for the wisest of all men, as we learn in the Cabala, had like you Jupiter in the Ascendant, nevertheless so powerful was the influence of his Saturn, though far weaker than yours, that one cannot find proof of his having laughed a single time in all his life. The Amateurs must, therefore, find fault with my Saturn and not with the Comte de GABALIS, if I prefer to divulge their secrets rather than to practise them.
I've been chekcing out a few cloud based mining sources like pool.bitcoin.com and I just can't seem to make heads nor tails of what to expect For example on the bitcoin pool site, it doesn't seem to matter if it's for 6 months, a year, or two years, at any TH/s, the price you pay is coming in at a net loss by the end of it. For example, 6 months of 500 TH/s for an upfront cost of $7,495 supposedly turns $31.48 worth of BCH per day (I understand the price fluctuates, this is the price the sites calculator gives me for today) But then when I check out what that's supposed to end up with that only winds up to being $5,745 worth of BCH 1 year of 100TH/s for an upfront cost of $2,500 is to earn about $6.30 worth of BCH per day, but only ends up being $2,300 earned after 365 days Is this the expectation, or is it just a bad day to be looking up these prices? I'm just wondering why i'd invest buy into these plans instead of, for example, trading? Sorry for the noobie question, please don't roast me too badly, i'm just confused right now Thank you
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.
Where can I buy bitcoins?
BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash. Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
