Bitcoin is not issued by a central authority but is automatically generated through a process called 'mining.' This mechanism is like a public competition that anyone with a computer and an internet connection can join. Participants use computing devices to solve complex mathematical problems, and the first one to find the solution receives new bitcoins as a reward. These participants are known as 'miners.'

The entire mining process is actually about maintaining the operation of the Bitcoin network. Whenever a Bitcoin transaction is initiated, the data is packaged into a 'block.' Miners then compete to be the first to verify this block and add it to the blockchain. The successful miner receives a 'block reward,' which is the source of new bitcoins.

This design not only makes Bitcoin issuance transparent and fair but also ensures the security and decentralization of the entire network. Over time, the bitcoin reward for miners gradually decreases, a process known as the 'halving.' Ultimately, the total supply of Bitcoin will be capped at 21 million coins.

While not everyone may be suited to participate in mining directly, understanding the logic behind it can help you grasp why Bitcoin differs from traditional currencies and gain a deeper insight into how digital assets operate.
