How Does Bitcoin Mining Work?

Bitcoin mining is in many ways similar to gold mining. This “digital mining” is a computer process that creates new bitcoins in addition to tracking bitcoin transactions and ownership. Both Bitcoin mining and gold mining are energy-intensive and both have the potential to generate substantial monetary returns.

Let’s delve into Bitcoin mining to understand how it works and how it affects Bitcoin transactions and Bitcoin investors.

What is Bitcoin Mining?

Bitcoin mining is a highly complex computational process that uses complex computer code to create a secure cryptosystem. Similar to the cryptography used by governments and spies, the cryptography used for mining generates bitcoins, facilitates bitcoin transactions, and tracks ownership of cryptocurrency assets. Bitcoin mining supports the Bitcoin database known as the blockchain.

Bitcoin miners are not people with pickaxes and shovels, but owners of sophisticated computer equipment. Bitcoin miners scramble to be the first to verify Bitcoin transactions and receive rewards paid in Bitcoin. Crypto miners must first invest in computer equipment dedicated to mining, and often require access to cheap power.

Competing miners race to complete challenging mathematical functions called hashes to process bitcoin transactions. A miner’s hash rate is the speed at which their computer configuration can solve mathematical equations. This mining protocol is known as proof-of-work because the first miner to prove they did “work” to solve a complex equation is granted the right to process the latest block of bitcoin transactions.

After a miner successfully validates a new block of transactions, the block is distributed to all other miners and any other devices that have a complete copy of the Bitcoin blockchain. (These devices are called nodes.) Many computers around the world maintain identical copies of the blockchain, ensuring the creation and maintenance of a trusted, verified history that is nearly impossible to crack or distort.


Why mine Bitcoin?

There are two main reasons for mining Bitcoin. One is to profit from Bitcoin mining, which is possible under the right circumstances. The second is to learn more about how cryptocurrencies work and support the continued work of the Bitcoin network. Let’s take a look at each of the reasons to mine Bitcoin:

Bitcoin mining profit

If you are interested in mining bitcoin yourself, known as solo mining, and want to make a profit, then you may need specialized mining hardware. Mining using a graphics processing unit (GPU) or an application-specific integrated circuit (ASIC) is usually the most efficient, but computers such as laptops or desktops can also be used (they rely on a central processing unit chip for their basic functions).

In addition to expensive hardware, you also need to consider internet bandwidth availability and local electricity bills. Bitcoin mining consumes a lot of electricity. To benefit from it, you need to use cheap electricity or solar panels on your roof. You also need an internet service provider that allows unlimited internet use without being charged for exceeding certain data limits.

Bitcoin mining for entertainment and education

If you enjoy tinkering with computers and learning new technologies, you might want to mine Bitcoin even if you’re not making any money. Setting up your own Bitcoin mining configuration allows you to understand the inner workings of your computer and the Bitcoin network.

How to Start Bitcoin Mining

Curious how to mine Bitcoin? Bitcoin mining is not easy, but anyone with intermediate to advanced computer skills may qualify. Once you’ve explored the potential to start Bitcoin mining, follow these basic steps:


Choose Your Bitcoin Mining Hardware

Your first step is to choose the hardware for mining Bitcoin. Many people start with an old computer to understand the fundamentals of Bitcoin mining. If you want to make money, it is important to use optimized mining hardware such as B. Graphics Processing Unit (GPU) or Application Specific Integrated Circuit (ASIC) miners.

Other minimum requirements for Bitcoin mining are a high-speed internet connection of at least 50 KB per second and no restrictions on uploading or downloading data. Bitcoin mining nodes typically use up to 200 GB of data per month for uploads and around 20 GB for downloads per month.

Deciding between Solo and Merged Mining

Next, you can decide whether to mine solo or cooperate with other miners. Since solo mining is unlikely to be consistently profitable, many join mining pools for more predictable crypto rewards.

Install and configure bitcoin mining software
Now is the time to install your bitcoin mining software. Depending on your hardware, operating system, and other factors, you can choose between different mining applications. Below are some of the most popular cryptocurrency mining software.

Start Bitcoin Mining

Once your mining rig is fully configured, you can start mining at the click of a button. Then sit back and watch your computer work hard to earn bitcoins. Miners typically need to run for at least 6 hours a day to be functionally successful, although keeping them running increases the likelihood of earning rewards from Bitcoin mining.

Monitor and optimize your mining equipment

Bitcoin mining is passive, but it’s not exactly set and done. You should monitor the performance and energy consumption of your mining equipment to ensure that your mining operations are running as efficiently and profitably as possible. Sometimes small configuration changes can significantly improve your revenue.


Risks and Limitations of Bitcoin Mining

If you decide to mine Bitcoin, consider the following risks and limitations:

Energy consumption

The Bitcoin network, including miners, nodes, and Bitcoin users, consumes more energy than many countries. As of January 16, 2022, the Bitcoin network consumes 131.00 TWh (or terawatt hours) of electricity per year, which means Bitcoin uses more electricity than countries like Norway and Ukraine, and slightly less than Egypt and Poland.

Bandwidth usage

Bitcoin miners are constantly downloading and uploading data. It is best to mine Bitcoin only with an unmetered, unrestricted internet connection. If you have to pay for every megabyte or gigabyte you use, or run into a data cap, similar to most cell phone plans, then you may be using more data than is allowed – your internet connection will drop or face additional charges. In general, most Bitcoin miners don’t use that much data all the time.

Hardware damage

Bitcoin mining is a very intensive process for a computer hardware unit. If your mining system is set up correctly, you don’t have to worry about hardware damage beyond normal wear and tear. But choosing the wrong hardware or running a poorly ventilated mining configuration can overheat and damage your machine.

Bitcoin Supply and Reward Limits

Bitcoin mining gets more difficult from time to time. Every year, the number of bitcoins created per block is halved. Once 21 million bitcoins have been minted, no new bitcoins will be created. From this point on, Bitcoin miners will only benefit from transaction fees.

When bitcoin was launched in 2009, the reward for successfully mining a block of bitcoin was 50 bitcoins. The first halving occurred in 2012 and reduced the mining reward to 25 bitcoins. Halvings have happened twice since 2012, most recently in May 2020. The current reward for mining a Bitcoin block is 6.25 BTC, with the next halving expected in 2024.


Like any other income-generating activity, Bitcoin mining profits are taxable. It’s important to keep track of cryptocurrency transactions for tax purposes, as ignoring tax responsibilities can get you into trouble with Uncle Sam.

Regional restriction

Bitcoin and Bitcoin mining are not legal anywhere. For example, China banned all cryptocurrency activity in 2021.8, be sure to understand the rules and regulations related to Bitcoin and other cryptocurrencies in the region where you live or are considering starting a mining business.

The Bottom Line on Bitcoin Mining

Bitcoin mining is critical to the functioning of Bitcoin. Miners are responsible for the vital work of validating transactions, tracking ownership of Bitcoin assets, and ensuring that the Bitcoin network remains secure. Almost anyone can participate with a computer capable of Bitcoin mining. Even if you don’t plan to mine, Bitcoin users can understand the fundamentals of Bitcoin mining.
