Most other calculators do NOT include this metric which makes mining appear way more profitable than it actually is. Bitcoin mining is a booming industry , but the Bitcoin price increasing can help make up some of these losses. The Bitcoin price is increasing at an average of 0. Try messing with the calculator using different prices. Hash rate — How many hashes per second can the Bitcoin miner make?
More hashes cost more, which is why efficiency is crucial. Right now, this is the Halong Mining Dragonmint T1. Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins. Price — How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important.
The fastest and more efficient mining hardware is going to cost more. The best ASIC miner is the most efficient bitcoin miner. Aim for value. Other bundled equipment may be included with your purchase depending on the seller. You can use a bitcoin mining profitability calculator to determine your estimated cost of return on your mining hardware. Be sure to take electricity costs into account. Most mining hardware appears profitable until electricity costs are accounted for.
The best way to determine actual profitability is to figure out your electricity cost per hash. That is really what will make or break your operation. Good Bitcoin mining hardware needs to have a high hash rate.
But, efficiency is just as important. To improve your efficiency, there are also companies that will let you order hardware to their warehouse and run the miners for you. You could also cloud mine bitcoins. But both options are a lot less fun than running your hardware! Halong Mining — Halong Mining is the newest mining hardware company. They have the best miner available.
Unfortunately, they already sold out of their first batch but a new batch should be available for sale soon. Bitmain — Bitmain makes the Antminer line of Bitcoin miners. Bitmain is based in China and also operates a mining pool.
BitFury — BitFury is one of the largest producers of Bitcoin mining hardware and chips. Its hardware is not available for purchase. Power Supply — Bitcoin rigs need special power supplies to funnel and use electricity efficiently. Cooling Fans — Bitcoin hardware can easily overheat and stop working. Buy a sufficient amount of cooling fans to keep your hardware working. Backup generators — You may want generators as a backup in case your main source of electricity goes down.
You can find Bitcoin mining equipment for sale on eBay. Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person. Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government. In the beginning, CPU s were used to solve cryptographic hash functions , until miners discovered that GPU s were far better equipped for mining.
As block difficulty increased, miners turned primarily to GPUs. Their hashrates are significantly higher than anything GPUs are capable of. With stellar performance comes a high price tag — the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin blocks were confirmed by the average person using their desktop — once ASICs hit the market, things changed. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person.
Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap. Thousands of ASICs all mine simultaneously in a mining farm large warehouse. Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be. Buy Antminer S7 on eBay. The S7 is also a popular choice among hobbyist miners for its reasonable price and strong performance. The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners.
The APW3 requires a minimum Volts to function and does not ship with the necessary 16A power cord. While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup. The S7-LN also excludes a cord. Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool. These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard.
With careful tweaking, it may be possible to profit from an S7 even at 15c power. The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:. Naturally, the hotter the environment, the more energy the fan s will consume to cool the unit. The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0. Setting them up via the MinerLink GUI is a simple process, requiring only your mining pool credentials to begin mining.
The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only. They are both cooled by dual fans. A dry basement is an ideal location. This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations.
Profits have accumulated where mining is most profitable China , with the result that several competing operations eg. KNC have been forced out of the industry. We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars. Even with free electricity we cannot see how they will ever get this money back.
The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market. With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged. Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:.
Can the new S9 change the game for smaller and hobby miners and restore their lost profitability? Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June.
However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe. Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future.
The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs. The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology.
The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices. Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. What does it mean in practice? Find more information about mining difficulty in our article Bitcoin mining in theory: what is the principle of mining? Bitcoin mining demands not only a lot of electric power but also a special place for a machine as mining rigs are noisy and emit a lot of heat.
The service miner housing provides a solution to this problem — you can place your machine into a professional data center and get rid of all these concerns. Nowadays, there are thousands of cryptocurrencies which differ by the used algorithm. A specialized mining rig can work only with a particular algorithm. If you buy an ASIC hardware to mine bitcoins you will also be able to mine other cryptocurrencies with the same algorithm e.
Bitshare, Bitcoin Cash or ByteCoin , but not cryptocurrencies based on a different algorithm. However, machines are constantly developing and some companies are starting to offer ASIC devices capable of solving multiple different algorithms e. Baikal Miner. Moreover, it is still possible to mine cryptocurrencies by graphics cards, if there is no specialized hardware to deal with a particular algorithm.
There are many advantages to mining by graphics cards — you can mine multiple cryptocurrencies and the machine produces much less noise and heat. Nevertheless, you have to take care of it and change cards regularly. The next important step is to set up a Bitcoin wallet. That's where you will receive your Bitcoins and will be able to manipulate with them. Bitcoin wallets allow you to manage your Bitcoin addresses Bitcoins themselves are technically stored in the Blockchain.
Each Bitcoin address has a form of a public key and matching private key. The public key comprises of a unique combination of characters and it looks for example like this: 18ukxpD1eqnVjux13ehEz8r4d8py1dSdzw. It works basically like a bank account number so if you want to receive Bitcoins from somebody, you have to tell him your public key. Every bitcoin address is public and you can trace back every transaction that passed through it. In contrast, the private key is secret and it serves to send off transactions.
If you lose your private key, you lose your Bitcoins placed on this particular address forever. In general, there are multiple types of wallets from simple online wallets, software ones to the most secure hardware and paper wallets. Each wallet has its advantages and disadvantages. Some of them can keep multiple currencies at the same time. The best option for starting miners is a software wallet. It is secure but still easy to manage and suitable for frequent manipulation with mined currency.
You easily download a wallet to your computer, where your coins will be stored and nobody can get to them. There are two kinds of software wallets: full ones which download the whole Blockchain or light-weight ones which store only relevant transactions. The first option requires a lot of space and memory in your computer but is definitely safer.
If you have decided to choose a full version of the wallet, you can download f. Take into account that its full synchronization takes a couple of hours because the Blockchain currently is the size of tens of GBs. If you prefer a wallet which can manage multiple currencies, you can try Exodus.
Miners provide their computing power to a group and when Bitcoins are mined, the gain is divided among members according to a given power. The income is lower but regular. You can choose from many pools, this graph from illustrates the representation of the biggest pools.
For better orientation, you can use the comparison of mining pools on Bitcoin Wiki. It is recommended for beginners to try Slush Pool , the very first pool in existence and is considered one of the most credible ones. As soon as you choose a mining pool, register yourself on its website and set your account.
Afterward, you will receive a worker ID for your miner. It connects you to the Blockchain and Bitcoin network. Mining software delivers work to miners, collects complete results of their work and adds all information back to the Blockchain. In general, there are many free programmes used to mine Bitcoins, the best programmes can run on almost all operational systems and each of them has its advantages and disadvantages. Some mining pools also have their own software.
Beginners will appreciate Nice Hash Miner. It is very easy to use, mines multiple cryptocurrencies and automatically chooses an algorithm which is the most profitable in a particular moment. Download the programme and choose a device you would like to mine with.
And now you can start mining and earning Bitcoins! Connect your miner to a power outlet, link it with computer and install mining software. Fill in your information about your wallet and mining pool into the mining software, choose a device, and let the mining begin! Some advice to send you off: if you want to mine profitably, keep track of the news from the crypto world.

They are doing the work of verifying the legitimacy of Bitcoin transactions. By verifying transactions, miners are helping to prevent the " double-spending problem. Double spending is a scenario in which a bitcoin owner illicitly spends the same bitcoin twice.
While there is the possibility of counterfeit cash being made, it is not exactly the same as literally spending the same dollar twice. If you were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false.
What a Bitcoin miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. This isn't a perfect analogy—we'll explain in more detail below. Once miners have verified 1 MB megabyte worth of bitcoin transactions , known as a "block," those miners are eligible to be rewarded with a quantity of bitcoin more about the bitcoin reward below as well.
The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size should be increased to accommodate more data, which would effectively mean that the bitcoin network could process and verify transactions more quickly.
It depends on how much data the transactions take up. That is correct. To earn bitcoins, you need to meet two conditions. One is a matter of effort; one is a matter of luck. This is the easy part. This process is also known as proof of work. The good news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems—that's not exactly true.
It's basically guesswork. The bad news: It's guesswork, but with the total number of possible guesses for each of these problems being on the order of trillions, it's incredibly arduous work. In order to solve a problem first, miners need a lot of computing power. That is a great many hashes. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare offers a helpful calculator.
In addition to lining the pockets of miners and supporting the bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of Nov. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin.
There will eventually come a time when Bitcoin mining ends; per the Bitcoin Protocol, the total number of bitcoins will be capped at 21 million. This does not mean that transactions will cease to be verified.
Miners will continue to verify transactions and will be paid in fees for doing so in order to keep the integrity of Bitcoin's network. Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol. The rewards for bitcoin mining are reduced by half every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC. By , this was halved again to If you want to keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real-time.
Interestingly, the market price of bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and historically the price has risen with it.
Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so.
However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate.
Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one. As of Nov. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC.
The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans. Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is. And there is no limit to how many guesses they get.
Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer.
Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin. Well, here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet.
Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine. In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine.
That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash.
What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that?
The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block was mined. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below.
As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block. If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros.
With bitcoin , the reward is halved every four years. You can join a bitcoin mining pool to be more effective, but that comes with a fee, reducing your profits. Some crypto miners instead opt for other currencies. Some other cryptocurrencies are worth very little in U. On top of building your rig, you also need to realize that you are going to be using quite a lot of power.
If you have high power rates, you could end up spending quite a lot to mine coins—especially bitcoin. A less powerful rig mining alternative currencies could save you money. Even so, it can take several weeks, or even months, to recoup your original investment and become profitable.
If you purchase a higher hash rate, you are expected to receive more coins for what you pay for, but it will cost more. Depending on the company you choose, you might pay a monthly fee, or you might pay according to the hash rate. In general, cloud miners that allow you access to bitcoin come at higher rates. In some cases, you might be required to sign a year-long contract, locking you in. If the value of the cryptocurrency drops, you could be stuck in an unprofitable contract.
As it is, depending on what you mine, it can take several months before your cloud mining investment becomes profitable. Buying bitcoins with hope of their value rising is equally risky. The market for cryptocurrencies is young, and for every analyst who sees great potential, there is another who expects the market to go bust.
Banks such as JP Morgan still view cryptocurrencies as unproven and likely to drop in value. Bitcoin and other cryptocurrencies remain a high-risk, high-reward investment with little consensus about the economic roles they will play in the coming years. Congressional Research Service.
