Mining is the method by which computers validate transactions and add them to a virtual public ledger called the blockchain. Using Bitcoin(BTC) as a case study, we will understand mining in crypto. In September of 2022, the reward for mining a block was 6.25 BTC, which is the equivalent of $125,000. In this post, we will discuss what is mining in crypto and all you need to know about mining crypto efficiently.
What is Mining Crypto?
Mining is the method by which computers validate transactions, it is a completely digital process that requires highly technical equipment, there are a lot of variables, and a high profit is not always guaranteed. Now, you must have heard that mining computers solve high-end equations and calculation, but this is not entirely true. The computers are merely guessing numbers, the first computer with the correct guess is declared the winner, and receives the reward.
The correct number is called “Hash”, and each digit in the hash has 16 probabilities(the digits 1 through 10 plus letters A through F). So, to generate a guess, you could roll a 16-sided die 64 times. That would give you one guess — the problem is, there are billions of possible results.
Why Mining Crypto?
While it serves as a means of income and supporting the ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically printing money.
Besides coins minted via the genesis block (the very first block created), every other coin came into being because of miners. In the absence of miners, networks like Bitcoin would still exist, but there would never be any additional bitcoin. However, because the rate of bitcoin “mined” is reduced over time, the final bitcoin won’t be circulated until around the year 2140. This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid fees for doing so in order to keep the integrity of Bitcoin’s network.
To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. This process is also known as proof of work (PoW).
Aside from the benefit of newly minted bitcoins, being a coin miner can also give you “voting” power when changes are proposed in the Bitcoin network protocol. This is known as a Bitcoin Improvement Protocol (BIP). This means that, miners have some degree of influence on the decision-making process for matters such as forking. The more hash power you possess, the more votes you have to cast for endeavors.
Why Are Miners Needed?
Blockchain “mining” is just a name for the computational work that systems in the network undertake in hopes of earning new tokens. In reality, miners are essentially getting paid for their work as auditors. They are doing the work of verifying Bitcoin transactions. This is meant to keep Bitcoin users honest. By verifying transactions, miners are helping to prevent the “double-spending” problem.
How Legal Is Mining Crypto?(Bitcoin Mining)
Bitcoin mining is legal in the United States. Some countries, such as Egypt, Nigeria, China and Qatar, have outlawed blockchain mining because it threatens national currencies. The legality of Bitcoin mining depends entirely on your geographic location, although Bitcoin use and mining remain legal across much of the globe.
How Much Do Bitcoin Miners Earn?
Block rewards are cut in half every 210,000 blocks (about every four years). That means the current reward of 6.25 BTC will be reduced to 3.125 BTC around 2024.
The dollar value of that reward can vary dramatically. Bitcoin, like any cryptocurrency, is volatile. Its value spikes and drops within short time periods.
So is bitcoin mining profitable? The bottom line is that there is no fixed amount bitcoin miners earn. Mining requires significant investment, and the results are unpredictable. It’s up to you to decide.
Bitcoin mining is popular for a reason. It’s an exciting way to earn money outside of a regular job.
It’s also important within the industry — miners contribute to the bitcoin ecosystem by validating transactions and putting new bitcoin into circulation. If there were no miners, there would be no new bitcoin.
Bitcoin Mining Requirements
Although individuals were able to compete for blocks with a regular personal computer early on in crypto mining 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 2,016 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.
The miner who discovers the hash 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. 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 regain their capital. The answer to this problem is mining pools.
Mining pools are operated by third parties 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.info.
A lot of miners choose to join mining pools: mining pools are groups that share their computing power and split the reward. Joining a pool improves your chances of solving the equation without having to invest in another bitcoin mining machine, but it also lowers the payout you receive as the reward is shared.
As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on the Bitcoin exchanges. Alternately, you can always leverage the “pickaxe strategy.” This is because,in the 1849 California Gold Rush, the smart investment was not to go dig for gold, but rather to make the pickaxes used for mining.
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. You may consider looking into companies that make ASIC equipment or GPUs instead.
Mining, especially Bitcoin mining can be a very expensive project to set up, whoever decides to go into it has to be intentional about his reasons due to the astronomical cost to setup a mining station, there is also the enormous electricity bill that comes with it.
However, it can also be quite lucrative, especially during the crypto bull-run when crypto prices are spiking.
