How to mine Bitcoin: A beginner’s guide to mine BTC
What is Bitcoin mining? Bitcoin mining explained
Bitcoin mining is the process of creating valid blocks that add transaction records to Bitcoin’s (BTC) public ledger, which is called a blockchain. It is a crucial component of the Bitcoin network as it solves the so-called “double-spend problem.”
The double-spend problem refers to the issue of needing to find consensus on a history of transactions. Ownership of Bitcoin can be proven mathematically through public-key cryptography. However, cryptography alone cannot guarantee that one particular coin hadn’t previously been sent to someone else.
To form a shared history of transactions, one needs to have an agreed-upon ordering that is based on, for example, the time of the creation of each transaction. But any external input can be manipulated by whoever provides it, requiring participants to trust that third party.
In this article, we will discuss what is crypto mining, how to mine Bitcoin, how Bitcoin mining works, the cost of mining Bitcoin, is Bitcoin mining illegal, and the various Bitcoin mining problems that miners face.
How does Bitcoin mining work?
Mining (blockchain mining, in general) leverages economic incentives to provide a reliable and trustless way of ordering data. The third parties ordering transactions are decentralized, and they receive monetary rewards for correct behavior. On the contrary, any misbehavior results in a loss of economic resources, at least as long as the majority remains honest.
In the case of Bitcoin mining, this result is achieved by creating a succession of blocks that can be mathematically proven to have been stacked in the correct order with a certain commitment of resources. The process hinges on the mathematical properties of a cryptographic hash — a way to encode data in a standardized manner.
Hashes are a one-way encryption tool, meaning that decrypting them to their input data is nearly impossible, unless every possible combination is tested until the result matches the given hash. So, how is Bitcoin mined?
This is what Bitcoin miners do: They cycle through trillions of hashes every second until they find one that satisfies a condition called “difficulty.” Both the difficulty and the hash are very large numbers expressed in bits, so the condition simply requires the hash to be lower than the difficulty.
Difficulty readjusts every 2016 Bitcoin block — or approximately two weeks — to maintain a constant block time, which refers to how long it takes to find each new block while mining.
The hash generated by miners is used as an identifier for any particular block and is composed of the data found in the block header. The most important components of the hash are the Merkle root — another aggregated hash that encapsulates the signatures of all transactions in that block — and the previous block’s unique hash.
This means that altering even the tiniest component of a block would noticeably change its expected hash — and that of every following block, too. Nodes would instantly reject this incorrect version of the blockchain, protecting the network from tampering.
Through the difficulty requirement, the system guarantees that Bitcoin miners put in real work — the time and electricity spent in hashing through the possible combinations. This is why Bitcoin’s consensus protocol is called “proof-of-work,” to distinguish it from other types of block-creation mechanisms. To attack the network, malicious entities have no method other than recreating the entirety of its mining power. For Bitcoin, that would cost billions of dollars.
But, how long does it take to mine 1 Bitcoin. One BTC typically takes around 10 minutes to create, although this is only true for strong processors. The Bitcoin mining hardware you use will determine how quickly you can mine.
Why mine Bitcoin?
In many aspects, Bitcoin mining is comparable to mining for gold. Crypto mining (in Bitcoin's case) is a computer operation that creates new Bitcoin and tracks transactions and ownership of the cryptocurrency. Bitcoin and gold mining are both energy-intensive and can produce significant financial rewards.
Therefore, you can mine BTC to earn profit/rewards. Some BTC miners build Bitcoin mining pools by combining their efforts with other miners. Groups of miners who work together have a more significant chance of earning rewards and splitting the profits. In addition, members of a mining pool pay a fee to be a part of the pool.
If your focus is not on money, you might want to mine Bitcoin if you enjoy playing with computers and learning about this new technology. For example, while doing Bitcoin mining configuration, you can learn how your computer and blockchain-based networks work.
Is Bitcoin mining worth it?
To find an answer to the above question, please conduct a cost-benefit analysis (using web-based calculators) to see whether Bitcoin mining is worth your effort. A cost-benefit analysis is a systematic method that organizations use to determine which actions should be undertaken and which should be avoided.
First, determine whether you are willing to invest the required initial capital in hardware and determine the future value of Bitcoin and the level of difficulty before committing your resources. It's also crucial to examine the amount of difficulty specific to the cryptocurrency you wish to mine to see if the mining operation would be even lucrative.
When both Bitcoin prices and mining difficulty fall, it usually means fewer miners are mining BTC and that acquiring BTC is easier. Nonetheless, expect more miners to compete for fewer BTC as Bitcoin prices and mining difficulty climb.
Is Bitcoin mining legal?
If you're wondering whether Bitcoin mining is legal — the answer is yes, considering the acceptance by various jurisdictions. For example, Enigma (based in Iceland) opened one of the world's most extensive Bitcoin mining operations.
Even though the block reward decreases over time, past halvings have been amply compensated by increases in the Bitcoin price. While this is no guarantee of future results, Bitcoin miners enjoy a relative degree of certainty about their prospects. The community is very supportive of the current mining arrangement and has no plans to phase it out like Ethereum, another major mineable coin. With the right conditions, individual Bitcoin miners can be confident that the venture will turn a profit.
