How Bitcoin Works
Bitcoin transactions are verified by network participants called miners, who use computational power to solve complex mathematical puzzles. This process, called mining, secures the network and adds new blocks to the blockchain. As a reward, miners receive newly minted Bitcoin along with transaction fees.

Bitcoin has a fixed supply of 21 million coins, with over 19 million already in circulation. This scarcity, combined with increasing demand, contributes to Bitcoin's value over time.
