How Does Bitcoin Mining Work? Ultimate Guide


The Antminer S19 series from Bitmain, based in China, is a powerful mining machine for Bitcoin. So, do you have a genuine understanding of the principles of Bitcoin mining? Why do we mine Bitcoin, and how much profit can be earned through mining? Why choose the Antminer S19 series for Bitcoin mining? Let’s dive in to find the answers.

With its decentralized structure and promise of financial independence, Bitcoin has recently come to be recognized as a revolutionary form of digital currency. A difficult procedure called “Bitcoin mining” is at the core of this digital currency. We’ll delve into the inner workings of Bitcoin mining in this blog post, looking at its fundamental ideas, workings, and function within the Bitcoin ecosystem.

Understanding Bitcoin

Cryptocurrencies are digital forms of money that can only be used online, and one of the most well-known types is Bitcoin. A distributed ledger that keeps track of cryptocurrency transactions, or a decentralized computer network, powers Bitcoin. New bitcoins are created, or mined, by network computers as they process and verify transactions. These networked computers, also known as “miners,” process the transaction in return for a Bitcoin payment.

Blockchain, the technology that underpins many cryptocurrencies, powers Bitcoin. A blockchain is a decentralized database that records every transaction made on a network. A block and chain are formed by joining sets of approved transactions. Consider it to be a long-running public record that functions somewhat like a receipt. Adding a block to the chain is the act of mining Bitcoin.

How Bitcoin Mining Works

The process of validating and logging transactions on the Bitcoin network is referred to as “mining” in this context. Adding new blocks to the blockchain and validating transactions to thwart fraud are the two main goals of Bitcoin mining. This decentralized process also results in the creation of new Bitcoins.

  • New bitcoins are created through the process of mining bitcoins, which involves checking new transactions against the Bitcoin network.
  • The process by which Bitcoin transactions are digitally verified on the Bitcoin network and added to the blockchain ledger is known as mining.
  • Blocks of transactions that are updated on the decentralized blockchain ledger are verified by resolving challenging cryptographic hash puzzles.

These puzzles require sophisticated tools and powerful computing power to solve. The term “bitcoin mining” refers to the process of rewarding miners with bitcoin that is later made available for use.

Understanding the Blockchain

The blockchain must be understood in order to fully comprehend Bitcoin mining. The blockchain is a distributed ledger that keeps track of all previous Bitcoin transactions. It functions as a clear and unchangeable database, preserving the reliability and safety of the Bitcoin network.

Why Bitcoin Needs Miners

Blockchain “mining” is a metaphor for the computational work that nodes in the network undertake in hopes of earning new tokens. Actually, miners essentially get paid for acting as auditors. They are completing the necessary checks to ensure that Bitcoin transactions are legitimate. Satoshi Nakamoto, the creator of Bitcoin, came up with this convention in order to keep users honest.

By verifying transactions, miners are helping to prevent the “double-spending problem.”

Double spending is the illegal use of the same Bitcoin twice by a Bitcoin owner. With physical money, this isn’t a problem: When you hand someone a $20 bill to buy a bottle of booze, you no longer have it, so there’s no chance you could use it to buy lottery tickets next door. Even though it is a possibility, using counterfeit money is not the same as literally using the same dollar twice. With digital currency, however, as the Investopedia dictionary explains, “there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original.”

Assume you had one $20 bill that was genuine and one $20 bill that was fake. Someone who took the time to check the serial numbers of both bills would notice that they were the same number, indicating that one of them had to be fake if you attempted to spend both the real and fake bills. An analogous task is performed by blockchain miners, who examine transactions to make sure users haven’t attempted to spend the same bitcoin twice inadvertently. The reason why this isn’t a perfect analogy is explained in more detail below.

Why Mine Bitcoin?

The only way to introduce new cryptocurrency into circulation is through mining, which also benefits the Bitcoin ecosystem and enriches the wallets of miners. In other words, miners are basically “minting” currency. For instance, out of a total of 21 million bitcoins, there were just under 19 million in use as of June 2023.

Every single one of those bitcoins was created by miners, with the exception of those that were created through the genesis block (the very first block, which was created by the project’s founder Satoshi Nakamoto). There would never be any more Bitcoin if there were no miners, but the Bitcoin network would still be present and functional. 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 imply that transactional verification will stop. In order to maintain the reliability of the Bitcoin network, miners will continue to verify transactions and receive rewards for their efforts.

To earn new bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. Another name for this procedure is proof of work (PoW). To start mining is to start doing this proof-of-work activity to solve the puzzle.

There isn’t much complex math or computation required. It’s possible that you’ve heard that miners solve challenging math problems, but this isn’t because the math is challenging in and of itself. What they’re actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a “hash”) that is less than or equal to the target hash. In essence, it is speculation.

So it is a matter of randomness, but it is incredibly laborious work given that there are trillions of possible guesses for each of these issues. And with each new miner that joins the mining network, the number of potential solutions (also known as the level of mining difficulty) only grows. Miners require a lot of computing power in order to solve a problem first. To mine successfully, you need to have a high “hash rate,” which is measured in terms gigahashes per second (terahashes per second (TH/s), and gigahertz (GH/s).

Aside from the short-term payoff of newly minted bitcoins, being a coin miner can also give you “voting” power when changes are proposed in the Protocol for the Bitcoin network. A Bitcoin Improvement Protocol (BIP) is what this is. In other words, miners have some degree of control over decisions regarding things like forking. You need to vote for such initiatives more often the more hash power you have.

How Much a Miner Earns

The term “Bitcoin halving” describes the division of block rewards in half, which lowers the reward given to miners for finding a block by half. The goal of halving is to maintain a stable price for Bitcoin by reducing inflation and the rate at which new Bitcoins are released into circulation. Following the mining of 210,000 blocks, or roughly every four years, the halving event takes place. The halving theory proposed by Satoshi Nakamoto in the Bitcoin protocol is used to determine how many Bitcoins are currently in circulation.

The initial reward for each block that was mined in Bitcoin was 50 Bitcoins. The block reward has changed three times to date, from 50 in 2009 to 25 in 2012 to 12.5 in 2016 to the current 6.25 BTC in 2020. On May 11th, 2020, the last Bitcoin halving took place.

By June 2023, 19 million of the maximum 21 million Bitcoins had been mined and put into use, or roughly 89.7% of all the Bitcoins that remained to be mined.

In the first few months of the year 2024, the next Bitcoin halving is anticipated to occur. Once all blocks are mined and the 21 million Bitcoin supply cap is reached, which is expected to happen in 2140, the halving should continue. After that, the only source of income for Bitcoin miners will be transaction fees.

How to Calculate Bitcoin Profit?

Miners must conduct a cost-benefit analysis to determine their break-even price before investing in pricey hardware or other mining equipment, putting aside the actual Bitcoin profit generated by mining.

Analyzing the cost incurred when purchasing Bitcoin currencies is necessary to determine the Bitcoin profit. The following step entails finding out how much 1 Bitcoin cost at the time of purchase and comparing it to its current value. The discrepancies between the new and old values will give a clear indication of the profit made.

Several factors that hinder Bitcoin’s profit are:

Cost of Power

Every season sees a change in electricity prices. Not only is electricity used to mine bitcoins, but it is also used to keep them from overheating and cool them down.


Mining doesn’t have a time limit. Since they can afford the mining costs, many miners operate continuously.

Bitcoin Value

Your Bitcoin profit and return on investment will be impacted by changes in the Bitcoin value, which are quantifiable.


Mining challenges can result from inefficient computers, low voltage, or any other factor.

Types of Bitcoin Mining

Mine Bitcoin in a number of different ways. As new hardware and consensus algorithms are developed, processes and equipment must adapt. The majority of the time, miners use specialized computing devices to solve challenging cryptographic equations. The most popular mining techniques will now be discussed.

CPU Mining

The hash operations necessary for the PoW model are carried out by central processing unit (CPU) mining, which uses a computer’s CPU. Early on, anyone could try to mine BTC and other cryptocurrencies because mining was cheap, had low entry barriers, and could be done with a standard CPU.

Profitable mining, though, got harder as more people started mining BTC and the network’s hash rate rose. Additionally, the development of specialized mining equipment with more powerful processing capabilities eventually rendered CPU mining all but impossible. Since all miners now use specialized hardware, CPU mining is probably no longer a practical option.

GPU Mining

A variety of applications can be processed simultaneously by graphics processing units (GPUs). They can be utilized for mining even though they are typically used for video games or graphics rendering.

Compared to the widely used ASIC mining hardware, GPUs are more flexible and reasonably priced. They can be used to mine some altcoins, but their effectiveness varies depending on the algorithm and mining difficulty.

ASIC Mining

How Does Bitcoin Mining Work? Ultimate Guide

ASICs are integrated circuits created specifically for one particular application. Specifically designed hardware used for mining is referred to by this term in the cryptosphere. The high efficiency and high cost of ASIC mining are well known. The price of an ASIC miner is much higher than that of a CPU or GPU because they are the most advanced mining devices available.

Additionally, as ASIC technology advances, older ASIC models may soon become unprofitable and require regular replacement. As a result, ASIC mining is among the priciest methods of mining even when electricity costs are not taken into account.

Mining Pools

The likelihood of discovering the right hash is very slim because a block reward is only given to the first successful miner. The likelihood of a miner with a small portion of the mining power independently finding the following block is extremely low. An answer to this difficulty is provided by mining pools.

To increase their chances of receiving block rewards, miners form mining pools to pool their resources (hash power). When the pool successfully locates a block, the miners in the pool split the reward based on how much work each one of them contributed.

In terms of hardware and electricity costs, Bitcoin mining pools can help individual miners, but because of their dominance in the industry, there have been worries about a potential 51% attack on networks.

How Do You Start Bitcoin Mining?

Here are the basics you’ll need to start mining Bitcoin:

  • Wallet. Any Bitcoin you earn as a result of your mining activities will be kept here. An encrypted online wallet is a place where you can store, send, and receive Bitcoin and other cryptocurrencies. Exodus, Trezor, and Coinbase are just a few businesses that provide cryptocurrency wallet options.
  • Mining software. It is possible to download mining software from a variety of different vendors for both Windows and Mac computers, and many of them are free to download. You can mine Bitcoin once the required hardware and the software are linked.
  • Computer equipment. The hardware is the part of Bitcoin mining that is most expensive. In order to successfully mine Bitcoin, you’ll need a strong computer that consumes a lot of electricity. The hardware costs typically range from $10,000 and up.

Risks of Bitcoin Mining

The risks associated with mining are frequently monetary and legal. As mentioned, mining involves a risk in terms of money because one might spend time and money buying mining equipment costing hundreds or thousands of dollars only to see no return on their investment. But by joining mining pools, this risk can be reduced. If you live in an area where mining is not allowed and are considering it, you should think twice. Before spending money on mining equipment, it may be a good idea to find out how your nation regulates cryptocurrencies and what people there think of them generally.

The increasing energy usage needed by the computer systems running the mining algorithms is another potential risk brought on by the growth of Bitcoin mining (and other PoW systems as well). Although ASIC chips have dramatically increased microchip efficiency, network expansion is outpacing technological advancement. There are issues with the environmental effects and carbon footprint of Bitcoin mining as a result.

Taxes on Bitcoin Mining

It’s critical to keep in mind how taxes may affect Bitcoin mining. Since asset prices have skyrocketed in recent years, the IRS has been attempting to crack down on cryptocurrency owners and traders. The most important taxes to remember when mining Bitcoin are listed below.

  • Are you a business? You might be able to write off expenses you incur for taxes if Bitcoin mining is your business. The amount of bitcoins you earn would be considered revenue. You probably won’t be able to deduct expenses if mining is your hobby though.
  • Bitcoin mined is money. If you are successful in mining Bitcoin or other cryptocurrencies, you will be taxed at ordinary income rates on the fair market value of the coins at the time of receipt.
  • Capital gains. It counts as a capital gain if you sell bitcoins for more than you paid for them and is taxed in the same way as traditional assets like stocks or bonds.

The security and efficiency of the Bitcoin network are greatly dependent on Bitcoin mining. It establishes consensus, ensures the accuracy of transactions, and permits the issuance of new Bitcoins. Even though it requires a lot of energy and is a complicated process, mining is still a vital part of the cryptocurrency ecosystem. The challenges posed by Bitcoin mining must be addressed, and its environmental impact must be reduced, by investigating novel and sustainable solutions.


How Many Bitcoin Had Been Mined?

What is the Maximum Number of Bitcoin Hat Can Exist?

21 million bitcoin
A strict cap was placed on the total number of Bitcoin that could ever exist when Satoshi Nakamoto invented it. There will never be more than 21 million bitcoin. The network’s nodes enforce this limit, referred to as the “hard cap,” which is written in the source code of Bitcoin.

Is Bitcoin Mining Legal?

The legality of mining bitcoins entirely depends on where you live. The dominance of fiat currencies and governmental control over the financial markets may be threatened by the idea of Bitcoin. Because of this, Bitcoin is completely prohibited in some locations.

More often than not, mining and Bitcoin ownership are legal worldwide. Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, and Pakistan are a few examples of countries where it was prohibited, per a 2018 report. Bangladesh, China, the Dominican Republic, North Macedonia, Qatar, and Vietnam are a few of the nations that have outlawed Bitcoin mining since 2018. Most of the world’s countries still permit the use and mining of bitcoins.

Can You Mine Bitcoin on Your IPhone?

No, in order to compete in the industry today, bitcoin mining needs a significant amount of computing and electrical power. Even if a mobile device is a part of a mining pool, running a miner on it is probably not going to bring in any money.

Does More Mining Increase the Price of Cryptocurrency?


Bitcoins are a form of decentralized digital currency, and their price solely depends on supply and demand. ( just like gold )

As opposed to other centralized cryptocurrencies, which tend to have heavily manipulated prices.

It has nothing to do with mining.
