Currently, Bitcoin coins are pretty popular in the e-commerce market. Many investors make huge profits by investing in Bitcoin. Instead of buying coins at a high cost, you can also manually mine them using computer algorithms. So exactly What is coin mining? How to mine coins at home to bring the highest efficiency?

What is Coin Mining?

Mining Coins, Coin plow, also known as Bitcoin mining, describes the fast processing and confirmation of payments on the bitcoin network. Mining Coins is like digging for gold, but we don’t have to use a pickaxe, but we dig them out with computer algorithms.

Thus, it can be said that bitcoin mining uses computers to detect BTC. To be able to mine Coins requires intelligence, experience, time, and, importantly, perseverance.

Bitcoin mining is done by an application installed on the computer so anyone can participate in the bitcoin mining system.

For example: On Bitcoin’s blockchain system, miners will confirm transaction information sent and received between users, including BTC quantity, time of sending and receiving, arrival address, outgoing address, … As soon as the confirmation is complete, this information will be included in a block. By mining these coins, new coins are created and added to the circulating supply of that coin. The most popular and earliest mined cryptocurrency is Bitcoin.

Why is it called bitcoin mining? 

It is called coin mining because this is the process to help you exploit the new Bitcoin system. Instead, the mining part is only part of the transaction confirmation process.

The main goal of mining is to maintain the decentralized ledger based on a form of decryption. Due to the law of probability, it is improbable that the same miner will yield a higher success rate.

How to participate in bitcoin mining

Anyone can participate in Bitcoin transactions, aka Blockchain. Investors need to guess a random number to solve the equation generated by the system. You do it right on your computer, so the more robust the computer, the higher the chances of winning.

If you guess correctly, you will earn bitcoins and continue writing about Bitcoin transactions on the Blockchain.

How does bitcoin mining work?

After mining, You will be paid their service reward, a new bitcoin every 10 minutes.

Many Bitcoin transactions are happening at the same time. These transactions are then included in the block. Once a block is verified, it is added to a previously confirmed chain of blocks, called the Blockchain.

How does bitcoin mining work?

When your mining computer gives the correct solution to a problem, your computer determines which pending transactions should be added to the next block of commerce on the Blockchain.

You will then temporarily be the owner of that bitcoin. The transaction block you created is sent to the entire network so other computers can validate it. Each computer that validates your solution updates its copy of the Bitcoin transaction ledger with the transactions you have chosen to include in the block.

All transactions in the Blockchain you just entered are now confirmed by the Bitcoin network and are virtually irreversible. In addition, you are paid any transaction fees attached to the transactions you inserted in the next block.

Difficulty increases

Of course, Bitcoin mining is not simple. Satoshi Nakamoto – The inventor of Bitcoin built the mining rules so that the more the network mines, the higher the difficulty increases, the more complicated the mining becomes.

The difficulty of the mining process is to self-regulate according to the accumulated mining power that the network possesses. When more miners are involved, it becomes more challenging to solve the problem. So how to adjust the difficulty?

Difficulty Adjustment 

We need to manually adjust the difficulty to create a steady stream of new Bitcoins into the system. That is, miners with more powerful hardware will win the computational settlement.

You can adjust the difficulty as follows: Mining difficulty is set to medium. A new block will be added every 10 minutes. Every 2016 block is generated (about 14 days) the difficulty is automatically fine-tuned by the network based on the capacity of the entire network. If less than 10 minutes, it will increase in difficulty. For more than 10 minutes, it will lower the difficulty. Also, keep the interval between newly generated blocks to 10 minutes.

What does Bitcoin mining cost include?

Bitcoin includes the following costs:

  • Computer hardware cost: Bitcoin mining hardware will be over 12 million VND (about 600 USD). And it will be much more expensive if you want to buy better hardware.
  • Electricity Consumption: Bitcoin mining uses a lot of electricity.
  • Use space: Cool place, room temperature to keep the machine cool (use the air conditioner, exhaust fan, etc.)
  • Take care of your system: you need to have the essential ability from Windows to install. To install software, know how to fix basic errors, and high-tech will need technical guidance.
