Bitcoin mining is the process of creating new bitcoins by solving extremely complicated math problems that verify transactions in the currency.
When a bitcoin is successfully mined, the miner receives a predetermined amount of bitcoin. But for most people, the prospects for Bitcoin mining are not good due to its complex nature and high costs. Here are the basics on how Bitcoin mining works and some key risks to be aware of. Bitcoin is one of the most popular types of cryptocurrencies, which are digital mediums of exchange that exist solely online. Bitcoin runs on a decentralized computer network or distributed ledger that tracks transactions in the cryptocurrency.
When computers on the network verify and process transactions, new bitcoins are created, or mined. These networked computers, or miners, process the transaction in exchange for a payment in Bitcoin. Bitcoin is powered by blockchain, which is the technology that powers many cryptocurrencies. A blockchain is a decentralized ledger of all the transactions across a network.
Groups of approved transactions together form a block and are joined to create a chain. Think of it as a long public record that functions almost like a long running receipt. Bitcoin mining is the process of adding a block to the chain. In order to successfully add a block, Bitcoin miners compete to solve extremely complex math problems that require the use of expensive computers and enormous amounts of electricity.
ASICs consume huge amounts of electricity, which has drawn criticism from environmental groups and limits the profitability of miners. If a miner is able to successfully add a block to the blockchain, they will receive 6. The reward amount is cut in half roughly every four years, or every , blocks. But the price of bitcoin has been highly volatile , which makes it difficult or impossible for miners to know what their payment might be worth whenever they receive it. It depends. The electricity for one ASIC can use the same amount of electricity as half a million PlayStation 3 devices, according to a report from the Congressional Research Service.
One way to share some of the high costs of mining is by joining a mining pool. Pools allow miners to share resources and add more capability, but shared resources mean shared rewards, so the potential payout is less when working through a pool. The IRS has been looking to crack down on owners and traders of cryptocurrencies as the asset prices have ballooned in recent years. Here are the key tax considerations to keep in mind for Bitcoin mining.
Your return is based on selling it to someone else for a higher price, and that price may not be high enough for you to turn a profit. How We Make Money. Editorial disclosure. Brian Baker.

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 1, transactions for this block.

All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty.
Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. To find such a hash value, you have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined Bitcoin.
Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions.
Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.
All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing. The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits. Source : CryptoCompare. The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network.
Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse.
The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners. Statistics on some of the mining pools can be seen on Blockchain. As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges.
Alternately, you can always leverage the "pickaxe strategy. To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment.
That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment.
One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms. Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress.
As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits.
Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control. Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort.
Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Because they are entirely digital records, there is a risk of copying, counterfeiting, or double-spending the same coin more than once. Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise "hack" the network. Indeed, it is far more cost-effective to join the network as a miner than to try to undermine it.
In addition to introducing new BTC into circulation, mining serves the crucial role of confirming and validating new transactions on the Bitcoin blockchain. This is important because there is no central authority such as a bank, court, government, or anything else determining which transactions are valid and which are not.
Instead, the mining process achieves a decentralized consensus through proof of work PoW. In the early days of Bitcoin, anybody could simply run a mining program from their PC or laptop. But as the network got larger and more people became interested in mining, the mining algorithm became more difficult.
This is because the code for Bitcoin targets finding a new block once every 10 minutes, on average. If more miners are involved, the chances that somebody will solve the right hash quicker increases, and so the difficulty increases to restore that minute goal. Now imagine if thousands, or even millions more times that mining power joins the network. That's a lot of new machines consuming energy. The legality of Bitcoin mining depends entirely on your geographic location.
The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not. Some examples of places where it was illegal according to a report were Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan.
Overall, Bitcoin use and mining remain legal across much of the globe. Because blockchain mining is very resource-intensive, it can put a large strain on your GPU or other mining hardware. In fact, it is not unheard of for GPUs to blow out, or for mining rigs to burst into flames. However, keeping your rigs running at a moderate pace and with sufficient power supplied, it is generally safe.
Bitcoin mining today requires vast amounts of computing power and electricity to be competitive. Running a miner on a mobile device, even if it is part of a mining pool, will likely result in no earnings. Bitcoin "mining" serves a crucial function to validate and confirm new transactions to the blockchain and to prevent double-spending by bad actors. It is also the way that new bitcoins are introduced into the system.
Based on a complex puzzle, the task involves producing proof of work PoW , which is inherently energy-intensive. This energy, however, is embodied in the value of bitcoins and the Bitcoin system and keeps this decentralized system stable, secure, and trustworthy. Bitmain Tech. Library of Congress.

It was, at the time, a unique solution to creating trust in a trustless environment. In this sense, mining is core to the security model of Bitcoin. The idea of mining and receiving BTC in return is an attractive sounding deal.
The goal of a miner is to find a valid block hash for their candidate block. A block hash is a string of numbers and letters that functions as a unique ID for each block. As soon as a miner finds a valid hash, they can validate their candidate block and collect the bitcoin rewards. This is also the moment that the blockchain transactions included in that block go from pending to confirmed. Another important metric is the energy consumption of a mining rig.
If you spend more money on electricity than the value earned mining, profitability goes out of the window. Theoretically, you could still try to mine bitcoins with your personal computer, but the chances of finding a valid hash are practically zero. Computing the hash function is relatively quick, but calculating the massive amount of random inputs takes much longer.
Some altcoins can still be mined with GPU cards. FPGA machines could also be an option depending on the mining algorithm, difficulty, and electricity costs. GPUs may serve different purposes, but they are basically used to process graphics and output them to a screen. They are able to divide complex tasks into several smaller ones to increase performance.
Some altcoins can be mined with GPUs, but the efficiency depends on the mining algorithm and difficulty. FPGA can be programmed and reprogrammed to serve different functions and applications. When joining a pool using your hardware locally, you will have to configure your software to partner with other miners. The process typically involves signing up for an account and connecting to a mining pool server. You can get an idea of how much profit you might get on the Binance Pool page.
BTC earnings are paid out daily into your Bitcoin wallet. If you want to avoid the more technical steps, you can also join a cloud-mining farm, leaving the hardware and software up to the farm owners. Broadly speaking, cloud mining usually consists of you paying for someone else to mine on your behalf. The farm owner is then expected to share the profits with you.
However, this option is very risky as there is no guarantee that you will get a return on your investment. Many cloud mining services turned out to be scams, so be careful. The initial investment for profitable mining is very high, and there are many risks involved. Your returns will also depend on market conditions and external factors like energy prices and hardware improvements.
