With the progress of technology, Bitcoin has gradually gained popularity as a virtual online currency, attracting countless investors. Bitcoin is understood to be trading at close to 30,000, so investors' enthusiasm for mining continues unabated. Let's take a look at the profit principle of coin mining.

Unlike most currencies today, the bitcoin monetary system exists on its own and does not rely on support or credit guarantees from central banks, governments or large corporations to operate. Bitcoin uses a distributed database spread across P2P network nodes to manage currency issuance, transactions and account balance information. Satoshi nakamoto uses the principles of cryptography to ensure that each bitcoin node agrees on an established protocol, thus ensuring the security of all aspects of the currency's circulation.
