  In the mining process of cryptocurrencies, the number 21 holds great significance, especially in the case of Bitcoin. It represents the maximum number of bitcoins that can ever be mined - 21 million. This finite supply is a key feature of Bitcoin and contributes to its value as a digital asset. Miners, who are responsible for validating transactions and securing the network, compete to solve complex mathematical puzzles. As a reward for their computational work, miners receive newly minted bitcoins. However, the reward for mining new blocks is halved approximately every four years through a process known as the 'Bitcoin Halving.' This gradual reduction in mining rewards ensures that the total supply of bitcoins will never exceed 21 million, making it a deflationary currency.
