How Bitcoin Mining Works

bitcoin miningWhere do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.
With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Bitcoin is Secure

Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

What is Bitcoin Mining?

What is the Blockchain?

Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.
This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

What is Proof of Work?

A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements.
Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.

What is Bitcoin Mining Difficulty?

The Computationally-Difficult Problem

Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.
This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.

The Bitcoin Network Difficulty Metric

The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.
As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.

The Block Reward

When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

How Bitcoin Mining Works?

Before you start mining Bitcoin, it's useful to understand what Bitcoin mining really means. Bitcoin mining is legal and is accomplished by running SHA256 double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second.
The Bitcoin network compensates Bitcoin miners for their effort by releasing bitcoin to those who contribute the needed computational power. This comes in the form of both newly issued bitcoins and from the transaction fees included in the transactions validated when mining bitcoins. The more computing power you contribute then the greater your share of the reward.

buy bitcoin mining hardware

Step 1 - Get The Best Bitcoin Mining Hardware

Purchasing Bitcoins - In some cases, you may need to purchase mining hardware with bitcoins. Today, you can purchase most hardware on Amazon. You also may want to check the bitcoin charts.

How To Start Bitcoin Mining

To begin mining bitcoins, you'll need to acquire bitcoin mining hardware. In the early days of bitcoin, it was possible to mine with your computer CPU or high speed video processor card. Today that's no longer possible. Custom Bitcoin ASIC chips offer performance up to 100x the capability of older systems have come to dominate the Bitcoin mining industry.
Bitcoin mining with anything less will consume more in electricity than you are likely to earn. It's essential to mine bitcoins with the best bitcoin mining hardware built specifically for that purpose. Several companies such as Avalon offer excellent systems built specifically for bitcoin mining.

Best Bitcoin Cloud Mining Services

Another option is to purchase in Bitcoin cloud mining contracts. This greatly simplifies the process but increases risk because you do not control the actual physical hardware.
Being listed in this section is NOT an endorsement of these services. There have been a tremendous amount of Bitcoin cloud mining scams.
Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s.
Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available.
Hashing 24 Review: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible.
Minex Review: Minex is an innovative aggregator of blockchain projects presented in an economic simulation game format. Users purchase Cloudpacks which can then be used to build an index from pre-picked sets of cloud mining farms, lotteries, casinos, real-world markets and much more.
Minergate Review: Offers both pool and merged mining and cloud mining services for Bitcoin.
Hashnest Review: Hashnest is operated by Bitmain, the producer of the Antminer line of Bitcoin miners. HashNest currently has over 600 Antminer S7s for rent. You can view the most up-to-date pricing and availability on Hashnest's website. At the time of writing one Antminer S7's hash rate can be rented for $1,200.
Bitcoin Cloud Mining Review: Currently all Bitcoin Cloud Mining contracts are sold out.
NiceHash Review: NiceHash is unique in that it uses an orderbook to match mining contract buyers and sellers. Check its website for up-to-date prices.
Eobot Review: Start cloud mining Bitcoin with as little as $10. Eobot claims customers can break even in 14 months.
MineOnCloud Review: MineOnCloud currently has about 35 TH/s of mining equipment for rent in the cloud. Some miners available for rent include AntMiner S4s and S5s.

bitcoin mining software

Step 2 - Download Free Bitcoin Mining Software

Once you've received your bitcoin mining hardware, you'll need to download a special program used for Bitcoin mining. There are many programs out there that can be used for Bitcoin mining, but the two most popular are CGminer and BFGminer which are command line programs.
If you prefer the ease of use that comes with a GUI, you might want to try EasyMiner which is a click and go windows/Linux/Android program.
You may want to learn more detailed information on the best bitcoin mining software.


Step 3 - Join a Bitcoin Mining Pool

Once you're ready to mine bitcoins then we recommend joining a Bitcoin mining pool. Bitcoin mining pools are groups of Bitcoin miners working together to solve a block and share in its rewards. Without a Bitcoin mining pool, you might mine bitcoins for over a year and never earn any bitcoins. It's far more convenient to share the work and split the reward with a much larger group of Bitcoin miners. Here are some options:
For a fully decentralized pool, we highly recommend p2pool.
The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.9.5 or later (0.10.2 or later recommended due to DoS vulnerabilities):


Step 4 - Set Up A Bitcoin Wallet

The next step to mining bitcoins is to set up a Bitcoin wallet or use your existing Bitcoin wallet to receive the Bitcoins you mine. Copay is a great Bitcoin wallet and functions on many different operating systems. Bitcoin hardware wallets are also available.
Bitcoins are sent to your Bitcoin wallet by using a unique address that only belongs to you. The most important step in setting up your Bitcoin wallet is securing it from potential threats by enabling two-factor authentication or keeping it on an offline computer that doesn't have access to the Internet. Wallets can be obtained by downloading a software client to your computer.
For help in choosing a Bitcoin wallet then you can get started here.
You will also need to be able to buy and sell your Bitcoins. For this we recommend:
  • SpectroCoin - European exchange with same-day SEPA and can buy with credit cards
  • Kraken - The largest European exchange with same-day SEPA
  • Buying Bitcoin Guide - Get help finding a Bitcoin exchange in your country.
  • Local Bitcoins - This fantastic service allows you to search for people in your community willing to sell bitcoins to you directly. But be careful!
  • Coinbase is a good place to start when buying bitcoins. We strongly recommend you do not keep any bitcoins in their service.

Step 5 - Stay Up To Date With Bitcoin News

Staying up to date with Bitcoin news is important for your bitcoin mining profits. If you want general Bitcoin news then we recommend the WeUseCoins news section.
There is the Bitcoin Mining News Section and these are the 5 most recent articles:

Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the reward equally according to the amount of shares they contributed to solving a block.
A "share" is awarded to members of the Bitcoin mining pool who present a valid proof of work that their Bitcoin miner solved. Bitcoin mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.
The solution to this problem was for miners to pool their resources so they could generate blocks quicker and therefore receive a portion of the Bitcoin block reward on a consistent basis, rather than randomly once every few years.

Network Consensus

bitcoin network consensus
If you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are in consensus with the Bitcoin network. The best way is to use the official BitCore client.
If you participate in a Bitcoin mining pool then you will want to ensure that they are engaging in behavior that is in agreement with your philosophy towards Bitcoin.
For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result in tremendous financial damage.
Therefore, it is your duty to make sure that any Bitcoin mining power you direct to a mining pool does not attempt to enforce network consensus rules you disagree with.

Segregated Witness

When segwit is activated, you will want to be able to mine and relay segwit-style blocks. The following mining software has been upgraded to support segwit.
Please note that software that supports the GetBlockTemplate (GBT) RPC must be upgraded to support the BIP9 and BIP145 changes to GBT. All the programs linked above that support GBT have been upgraded.
Segwit is already activated and enforced on testnet, so you may find it useful to test your infrastructure upgrade by mining with some small amount of hashrate on testnet. Alternatively, Bitcoin Core 0.13.1’s regression test mode (regtest) also supports segwit by default.

Bitcoin Mining Pools

There are many good Bitcoin mining pools to choose from. Although it's tempting to pick the most popular one, it's better for the health of the network to mine with smaller pools so as to avoid potentially harmful concentration of hashing power.
The hash rate distribution is best when split among more Bitcoin mining pools.

Bitcoin Mining Pool Hash Rate Distribution

Bitcoin Mining Pool Options

For a fully decentralized pool, we highly recommend p2pool.
The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.11 or later:
BTCC: BTCC is a Bitcoin exchange, wallet, and mining pool located in China. Its mining pool currently controls around 15% of the network hash rate.
Slush Pool: Slush Pool is run by Satoshi Labs, a Bitcoin company based in the Czech Republic. Slush Pool was the first mining pool and maintains around 7% of the network hash rate.
Antpool: [WARNING] - Bitmain operates Antpool and some consider them to be a malicious actor in the Bitcoin ecosystem because of the AntBleed scandal where they were intentionally including malware within mining equipment they sell. In a corporate communication, Bitmain claimed this was a feature and not a bug. This malware would enable Bitmain to remotely shut down equipment of customers or competitors thus increasing their own profitability. Additionally, such behavior could pose a risk to the entire Bitcoin network.
Eligius: Eligius was one of the first Bitcoin mining pools and was founded by Luke Dashjr, a Bitcoin Core developer. Today, the pool controls just under 1% of the network hash rate.
BitMinter: BitMinter, once one of the largest Bitcoin mining pools, now controls less than 1% of the network hash rate.
Kano CKPool: Kano CKPool was founded in 2014 and currently has around 3% of the network hash rate under its control.
F2Pool: F2Pool is the second largest Bitcoin mining pool, with around 25% of the network hash rate. Its user interface is in Chinese, making it difficult for English speakers to join.
BW Pool: BW Pool controls around 7% of the network hash rate. Like F2Pool, its user interface is in Chinese, making it difficult for English speakers to join.
Bitfury: Although seen publically in block explorers and hash rate charts, BitFury is a private mining pool and cannot be joined.

Bitcoin Mining Pool Payment Methods

Calculating your share of the bitcoins mined can be complex. In an ongoing effort to come up with the fairest method and prevent gaming of the system, many calculation schemes have been invented. The two most popular types are PPS and DGM. PPS, or 'pay per share' shifts the risk to the mining pool while they guarantee payment for every share you contribute.
PPS payment schemes require a very large reserve of 10,000 BTC in order to ensure they have the means of enduring a streak of bad luck. For this reason, most Bitcoin mining pools no longer support it.
One of the few remaining PPS pools is EclipseMC. DGM is a popular payment scheme because it offers a nice balance between short round and long round blocks. However, end users must wait for full round confirmations long after the blocks are processed.
PPS: The Pay-per-Share (PPS) approach offers an instant, guaranteed payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.
PROP: The Proportional approach offers a proportional distribution of the reward when a block is found amongst all workers, based off of the number of shares they have each found.
PPLNS: The Pay Per Last N Shares (PPLN) approach is similar to the proportional method, but instead of counting the number of shares in the round, it instead looks at the last N shares, no matter the boundaries of the round.
DGM: The Double Geometric Method (DGM) is a hybrid approach that enables the operator to absorb some of the risk. The operator receives a portion of payouts during short rounds and returns it during longer rounds to normalize payments.
SMPPS: The Shared Maximum Pay Per Share (SMPPS) uses a similar approach to PPS but never pays more than the Bitcoin mining pool has earned.
ESMPPS: The Equalized Shared Maximum Pay Per Share (ESMPPS) is similar to SMPPS, but distributes payments equally among all miners in the Bitcoin mining pool.
RSMPPS: The Recent Shared Maximum Pay Per Share (RSMPPS) is also similar to SMPPS, but the system prioritizes the most recent Bitcoin miners first.
CPPSRB: The Capped Pay Per Share with Recent Backpay uses a Maximum Pay Per Share (MPPS) reward system that will pay Bitcoin miners as much as possible using the income from finding blocks, but will never go bankrupt.
BPM: Bitcoin Pooled mining (BPM), also known as "Slush's pool", uses a system where older shares from the beginning of a block round are given less weight than more recent shares. This reduces the ability to cheat the mining pool system by switching pools during a round.
POT: The Pay on Target (POT) approach is a high variance PPS that pays out in accordance with the difficulty of work returned to the pool by a miner, rather than the difficulty of work done by the pool itself.
SCORE: The SCORE based approach uses a system whereby a proportional reward is distributed and weighed by the time the work was submitted. This process makes later shares worth more than earlier shares and scored by time, thus rewards are calculated in proportion to the scores and not shares submitted.
ELIGIUS: Eligius was designed by Luke Jr., creator of BFGMiner, to incorporate the strengths of PPS and BPM pools, as miners submit proofs-of-work to earn shares and the pool pays out immediately. When the block rewards are distributed, they are divided equally among all shares since the last valid block and the shares contributed to stale blocks are cycled into the next block's shares. Rewards are only paid out if a miner earns at least. 67108864 and if the amount owed is less than that it will be rolled over to the next block until the limit is achieved. However, if a Bitcoin miner does not submit a share for over a period of a week, then the pool will send any remaining balance, regardless of its size.
Triplemining: Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which allows your share to grow faster than any other Bitcoin mining pool approach. The administrators of these Bitcoin mining pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. In this way, everyone in the pool has a better chance to make additional Bitcoins, regardless of their processing power.

Best Bitcoin Cloud Mining Contracts and Comparisons

Bitcoin cloud mining contracts are usually sold for bitcoins on a per hash basis for a particular period of time and there are several factors that impact Bitcoin cloud mining contract profitability with the primary factor being the Bitcoin price.
For example, Pay per GHash/s would be 0.0012 BTC / GHs for a 24 month contract.
Contracts vary from hourly to multiple years. The major factor that is unknown to both parties is the Bitcoin network difficulty and it drastically determines the profitability of the bitcoin cloud hashing contracts.
Bitcoin network difficulty is a measure of how difficult it is to find a hash below a given target.
The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target. Bitcoin mining pools also have a pool-specific share difficulty setting a lower limit for shares.
The Bitcoin network difficulty changes roughly every two weeks or 2,016 blocks.

Bitcoin Mining Software Guide

bitcoin chart going up arrow
While the actual process of Bitcoin mining is handled by the Bitcoin mining hardware itself, special Bitcoin mining software is needed to connect your Bitcoin miners to the blockchain and your Bitcoin mining pool as well, if you are part of a Bitcoin mining pool.
The software delivers the work to the miners and receives the completed work from the miners and relays that information back to the blockchain and your mining pool. The best Bitcoin mining software can run on almost any operating system, such as OSX, Windows, Linux, and has even been ported to work on a Raspberry Pi with some modifications for drivers depending on your mining setup.
Not only does the Bitcoin mining software relay the input and output of your Bitcoin miners to the blockchain, but it also monitors them and displays general statistics such as the temperature, hashrate, fan speed, and average speed of the Bitcoin miner.
There are a few different types of Bitcoin mining software out there and each have their own advantages and disadvantages, so be sure to read up on the various mining software out there.

Network Consensus

bitcoin network consensusIf you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are in consensus with the Bitcoin network. The best way is to use the official BitCore client.
If you participate in a Bitcoin mining pool then you will want to ensure that they are engaging in behavior that is in agreement with your philosophy towards Bitcoin.
How much bandwidth does Bitcoin mining take? If you are mining with a pool then the amount should be negligible with about 10MB/day. However, what you do need is exceptional connectivity so that you get any updates on the work as fast as possible.
For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result in tremendous financial damage.
Therefore, it is your duty to make sure that any Bitcoin mining power you direct to a mining pool does not attempt to enforce network consensus rules you disagree with.

Bitcoin Wallet Software

The whole point of mining bitcoins is to earn them!
But once you earn them then where do you keep them safe and secure? For a Bitcoin wallet we highly recommend using one where you hold your own private keys in contrast to to a hosted wallet like Coinbase or Circle.
  • Breadwallet - easy to use mobile Bitcoin wallet
  • Copay - easy to use mobile Bitcoin wallet
  • Armory - highly secure desktop Bitcoin wallet
You will also need to be able to buy and sell your Bitcoins.
Once mined Bitcoin becomes like a currency that can be purchased, used in transactions or even traded like with this Bitcoin trading platform.
For this we recommend:
  • Kraken - The largest European exchange with same-day SEPA
  • Local Bitcoins - This fantastic service allows you to search for people in your community willing to sell bitcoins to you directly. But be careful!

TRANSCRIPT - Do it yourself with Bitcoin mining software

What's going on every one? This is Fredand this Part 2 of our DIY Bitcoin Miner. Today, we're going to take a look at software.
Okay, so the first thing that you need to do before you could start Bitcoin mining is to sign up for a Bitcoin wallet. Now there’s a lot of wallets that you could choose from but I prefer Circle. Now let’s head over and set up an account. All you have to do is enter in your email and choose a password.
Once you log in to your account you will see a summary of your Bitcoin balance and transactions. But before you can receive any Bitcoins you need to set up a Bitcoin address. You could do so by clicking account settings.
Once you are on the account settings page go ahead and click Bitcoin Addresses. From there click Create New Address. This generates a long string of numbers and letters. This is the address that we will need to enter into our mining pool. So let's take a look at that now.
There are many mining pools that you can choose from, but I prefer BitMinter as my primary pool and Slush’s pool as my backup. Just create an account whichever one you choose and log in. Your account details page will normally have an auto cash out option.
This is where we will enter in our wallet address that we created earlier. When you have mined enough Bitcoins to meet the threshold it would automatically be transferred to your Bitcoin wallet.
Next, go up top to the My Account drop down and select Workers. This worker information is what you need to input into the mining software so that you get credit for the work that is done. You do not need to secure this information with a difficult username or password because anyone that uses this information will be giving you credit.
Now let's take a look at setting up the mining software. As mentioned in Part 1 of the series we'll be using the MinePeon operating system. This can be downloaded from sourceforge.net.
Now this is the image that we will need to write onto our SD card. Another software that we need to download is called the Win32 Disk Imager. This can also be found on sourceforge.net. This is the software that we will use to write the MinePeon image onto our SD card.
Once you have downloaded both files insert your SD card into your computer. Then open up Win32 Disk Imager. Simply select the location of your MinePeon image then select the correct drive for your SD card. All you have to do now is click write. This will write the MinePeon image on to your SD card. Insert the SD card into your Raspberry Pi as shown on Part 1 of the series then power up the unit.
Now sign in to MinePeon by typing in the network IP address into your browser. The easiest way to find this IP address is by logging in to your router and looking for the device called MinePeon. You will then be prompted to enter in your MinePeon's username and password. The default setting for this is MinePeon for the username, peon for the password. You will see a security warning but do not be alarmed. This is perfectly normal so proceed anyways. You will then be asked to re-enter the username and password.
So again, MinePeon is the username peon is the password. You are now finally in MinePeon's dashboard. This is where you can monitor the performance of your mining rig. Head up top and click pools. This page allows you to set up your mining pools. As you can see I have BitMinter as my primary pool and Slush’s pool as my secondary. Just enter in the URL of your mining pool, the username and password if you have one.
Then go ahead and submit your settings. You may need to reboot MinePeon after any changes. Great job every one. You are now officially mining for Bitcoins.
All right, so that should be everything that you need to start Bitcoin mining.

Bitcoin Mining Hardware Guide

bitcoin mining chips

The best Bitcoin mining hardware has evolved dramatically since 2009

At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work.
During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection.
FPGA miners used much less power than CPU's or GPU's and made concentrated mining farms possible for the first time.

Today's modern and best bitcoin mining hardware

Application-specific integrated circuit (ASIC) miners have taken over completely. These ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs. Several reputable companies have established themselves with excellent products.

Best Bitcoin Mining Hardware

bitcoin mining chip sheet Two major factors go into determining the best bitcoin mining hardware: (1) cost and (2) electricity efficiency.
Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot.

ASIC Bitcoin Mining Hardware

Application-specific integrated circuit chips (ASICs) are bitcoin mining hardware created solely to solve Bitcoin blocks. They have only minimal requirements for other normal computer applications. Consequently, ASIC Bitcoin mining systems can solve Bitcoin blocks much quicker and use less less electricity or power than older bitcoin mining hardware like CPUs, GPUs or FPGAs.
As Bitcoin mining increases in popularity and the Bitcoin price rises so does the value of ASIC Bitcoin mining hardware. As more Bitcoin mining hardware is deployed to secure the Bitcoin network the Bitcoin difficulty rises. This makes it impossible to profitably compete without a Bitcoin ASIC system. Furthermore, Bitcoin ASIC technology keeps getting faster, more efficient and more productive so it keeps pushing the limits of what makes the best Bitcoin mining hardware.
Some models of Bitcoin miners include Antminer S5, Antminer U3, ASICMiner BE Tube, ASICMiner BE Prisma, Avalon 2, Avalon 3, BTC Garden AM-V1 616 GH/s, VMC PLATINUM 6 MODULE, and USB miners.
