1. What is Bitcoin Mining?
Bitcoin mining is a complex process through which Bitcoin transactions are validated and new Bitcoins are created. When we hear the term mining, the first thing we are likely to think about is minerals like iron ore, copper, or even gold. We generally don't associate mining with currencies or payment systems. Mining US dollars or euros sounds pretty odd.
So, how is mining associated with digital currencies like Bitcoins? The short answer is that the way digital currencies work is fundamentally different from the working of fiat currencies like the dollar. You can find basic information on what Bitcoin is and how it works in our article dedicated to this topic and below, we are going to take a short detour to first understand how blockchain works before delving deep into BTC mining.
Cryptocurrencies exist within blockchains. A blockchain is a distributed ledger on which all participants can record and validate transactions. In blockchains, transaction data is recorded in blocks which are then chronologically connected to each other. Since there is no single authority to check the blocks and validate the transactions, this work is done by participants through a voting process called consensus mechanism. Mining is associated with the Proof-of-Work (PoW) consensus mechanism, which is also the most common consensus protocol.
Since Bitcoin runs on PoW, it involves mining. Bitcoin mining is the process through which participants in the Bitcoin blockchain validate Bitcoin transactions and complete the blocks. Each time a new block is created, the miner gets a certain amount of Bitcoin as a reward. The current reward for mining 1 block is 6.25 BTC
2. How Does Bitcoin Mining Work?
You must be thinking about why to mine Bitcoin in the first place or how crypto mining works. This guide on how cryptocurrency mining works gives you an overview of the mining process. The primary reason behind Bitcoin mining is to have a foolproof system for validating Bitcoin transactions. Without proper validation, the information recorded on the Bitcoin blockchain will have no credibility.
The process of validating transactions is pretty complex, so for those who are not familiar with crypto, we would rather recommend our guide including crypto trading strategies for beginners. In case of Bitcoin mining, one needs to solve complex mathematical puzzles (which are done by computers) to validate transactions. So, when we say someone is mining Bitcoin, what we essentially mean is that someone is solving complex math problems to validate Bitcoin transactions. Leaving the technical details out, solving mathematical puzzles in mining involves guessing a 64-digit hexadecimal number to complete blocks. You need the best computers of the day to do that! All the participating computers race to guess this number. Whichever one guesses it first gets a chance to complete the next block.
Solving these mathematical puzzles needs sophisticated computer systems (which can easily cost over $10k). So, why would someone spend so much to validate a transaction? Let’s look at the other part of the puzzle, which is the mining rewards.
When you validate transactions, you get block rewards. Currently, Bitcoin’s block reward is 6.25 BTC. So, when you participate in Bitcoin mining and complete 1 block, you get 6.25 BTC as a reward for your efforts and investment in computing power. Its current market value is about $220,000 (October 2023). Sounds pretty cool right? Wait - there is more to it than meets the eye.
2.1 Increasing complexity and Bitcoin halving
As more and more miners enter the Bitcoin mining business and more computing power is deployed, the puzzles get more complex to solve. Satoshi Nakamoto designed Bitcoin in such a way that the time required to create a block stays roughly 10 minutes. This helps in stabilizing BTC’s supply while maintaining its security.
The total supply of Bitcoin is fixed at 21 million BTC. So, the block reward is cut in half after every 210,000 blocks (which takes roughly 4 years). This event is called Bitcoin halving. When BTC was first created, the block rewards were 50 BTC, which then fell to 25 BTC, 12.5 BTC, and finally to 6.25 BTC with subsequent halving events. The next Bitcoin halving event is expected in 2024.
Bitcoin halving is going to ensure that when all the 21 million Bitcoins have been mined, there is no incentive to mine more BTC. The block rewards at this point will fall to zero. So, why will someone still validate transactions as it’s essential for the BTC blockchain to continue? The answer is that the validators will earn transaction fees.
3. Purposes of Bitcoin Mining
Once you learn what Bitcoin is, how to buy Bitcoin and how Bicoin mining works, let's find out what is the aim of this process. Bitcoin mining serves a number of purposes:
- It ensures that the BTC network is secure and all transactions are properly validated.
- Mining eliminates the problem of double spending by bad actors in the network.
- Bitcoin mining helps maintain the BTC blockchain.
- BTC mining creates new BTC into circulation in a controlled way.
As you can see there are a few functions of BTC mining. But you may ask yourself what's in it for me. We provide the answer to this question in the next paragraph.
4. Why Mine Bitcoin?
The main reason you would like to mine Bitcoin is to get the mining rewards. As we just discussed, currently you get to earn 6.25 BTC for completing 1 block, which you can later spend in one of the best Bitcoin and crypto casinos we recommend in our article. Therefore, Bitcoin mining can be a lucrative source of income provided that you have the technical know-how and all the resources in place.
Also, it’s mostly a passive income as you can automate the Bitcoin mining process using advanced software.
