Sometimes it is easier to understand how things work when we can visualize where the work is taking place, what is required to drive the work, and who or what is involved. We will take a look at some of those questions here in order to help you better understand how crypto mining works.

While traditional mining took place in a physical mine or specific geographic place, crypto mining takes place in a decentralized system where anyone with a computer and power source пїЅ anywhere in the world пїЅ can be a part of the digital data recordkeeping required for cryptocurrency transactions. The shared, publicly available cryptocurrency record is called a ledger. With traditional currency, the ledger is centralized, meaning only official authorities and banks can verify and validate transactions and values.

In the decentralized cryptocurrency system, the responsibility for verifying and validating transactions and recording the digital data on the ledger is distributed among all of the participants on the cryptocurrency network. For this reason, it is called a distributed network. The decentralized network functions like a web, with many people and computers taking part and participating, so no one institution or person can control the network.

As previously discussed, cryptocurrency uses distributed ledger technology to decentralize currency transactions. That ledger is called a blockchain.

At the same time, competition among miners rises, increasing the scarcity of cryptocurrency as a result. Mining cryptocurrencies requires computers with special software specifically designed to solve complicated, cryptographic mathematic equations.

Over the years, however, CPU chips have become impractical for mining most cryptocurrencies due to the increasing difficulty levels. In addition, the GPUs in the mining rig must be connected to a reliable internet connection at all times.

Each crypto miner is also required to be a member of an online crypto mining pool as well. Different methods of mining cryptocurrencies require different amounts of time. However, many find CPU mining to be too slow and impractical today because it takes months to accrue even a small amount of profit, given the high electrical and cooling costs and increased difficulty across the board.

GPU mining is another method of mining cryptocurrencies. It maximizes computational power by bringing together a set of GPUs under one mining rig. For GPU mining, a motherboard and cooling system is required for the rig. Similarly, ASIC mining is yet another method of mining cryptocurrencies. However, they are expensive, meaning that, as mining difficulty increases, they quickly become obsolete.

Cloud mining allows individual miners to leverage the power of major corporations and dedicated crypto-mining facilities. Individual crypto miners can identify both free and paid cloud mining hosts online and rent a mining rig for a specific amount of time. This method is the most hands-free way to mine cryptocurrencies. Mining pools allow miners to combine their computational resources in order to increase their chances of finding and mining blocks on a blockchain. If a mining pool succeeds, the reward is distributed across the mining pool, in proportion to the amount of resources that each miner contributed to the pool.

Most crypto mining applications come with a mining pool; however, crypto enthusiasts now also join together online to create their own mining pools. Because some pools earn more rewards than others, miners are free to change pools whenever they need to. Miners consider official crypto mining pools more reliable since they receive frequent upgrades by their host companies, as well as regular technical support.

The best place to find mining pools is CryptoCompare , where miners can compare different mining pools based on their reliability, profitability, and the coin that they want to mine. Determining whether crypto mining is worthwhile depends on several factors. Generally, crypto-mining machines consume a considerable amount of electricity and emit significant heat.

For instance, the average ASIC miner will use about 72 terawatts of power to create a bitcoin in about ten minutes. These figures continue to change as technology advances and mining difficulty increases. Even though the price of the machine matters, it is just as important to consider electricity consumption, electricity costs in the area, and cooling costs, especially with GPU and ASIC mining rigs.

It is also important to consider the level of difficulty for the cryptocurrency that an individual wants to mine, in order to determine whether the operation would even be profitable. The taxation of crypto mining remains an important consideration. Crypto miners will generally face tax consequences 1 when they are rewarded with cryptocurrency for performing mining activities, and 2 when they sell or exchange the reward tokens.

With respect to 1 , the IRS has issued Notice which directly addresses the tax implications of crypto mining. Under the Notice, a miner will recognize gross income upon receipt of the reward tokens in an amount equal to the fair market value of the coins at the time of receipt.

For a more detailed analysis of crypto mining tax implications, see Taxation of Crypto Mining. Most jurisdictions and authorities have yet to enact laws governing cryptocurrencies, meaning that, for most countries, the legality of crypto mining remains unclear.

Under the Financial Crimes Enforcement Network FinCEN , crypto miners are considered money transmitters, so they may be subject to the laws that govern that activity. In Israel, for instance, crypto mining is treated as a business and is subject to corporate income tax.

In India and elsewhere, regulatory uncertainty persists, although Canada and the United States appear friendly to crypto mining.

However, apart from jurisdictions that have specifically banned cryptocurrency-related activities, very few countries prohibit crypto mining. Our Freeman Law Cryptocurrency Law Resource page provides a summary of the legal status of cryptocurrency for each country across the globe with statutory or regulatory provisions governing cryptocurrency. For aspiring crypto miners, curiosity and a strong desire to learn are simply a must.

In , this was halved to 25 BTC. By , this was halved again to On May 11, , the reward halved again to 6. Not a bad incentive to solve that complex hash problem detailed above, it might seem.

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. 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.

Other web resources offer similar tools. Although individuals were able to compete for blocks with a regular at-home personal computer early on in Bitcoin's history, 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 blockchain functions smoothly and can process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so.

However, if there are 1 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 bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate.

Less computing power means the difficulty level decreases. At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC.

Some minersпїЅparticularly Ethereum minersпїЅbuy individual graphics cards as a low-cost way to cobble together mining operations. Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins.

Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed.

Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it. 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.

If B and C both answer simultaneously, then the system breaks down. 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 haven't verified the most transactions are not rewarded with bitcoin.

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.

The decimal system uses factors of as its base e. This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or 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. 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 analogy, in which the number 19 was written on a piece of paper and put 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.

Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning. In Bitcoin mining, a nonce is 32 bits in sizeпїЅmuch smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6.

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 No. 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 1, transactions for this block. If you really want to see all 1, of those transactions for this block, go to this page and scroll down to the Transactions section.

Source : Blockchain. 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 poolпїЅa 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.

Demand drives innovation. Things will happen in the Bitcoin mining space that you couldn't possibly imagine. Created in , much of the hype around Bitcoin relates to the trading of the currency. Remember, Bitcoin is the most divisible currency in the world. Comparatively, when you mine crypto, the process is a little different.

I have been writing about all aspects of household finance for over 30 years, aiming to provide information that will help readers make good choices with their money. Each time a miner adds a new block of transactions to the blockchain, they earn 6.

The dollar value of that amount fluctuates with the value of bitcoin. China is the country with the largest mining capacity in the world. The obvious consequence is excessive energy consumption which will be million metric tons of carbon by in China alone. How does crypto mining work? May
