Bitcoin uses proof-of-work consensus, where miners validate transactions and secure the network in exchange for rewards. With a fixed supply of 21 million coins, Bitcoin is often seen as “digital gold” and a hedge against inflation. It is widely used for investment, trading, and storing value. Despite volatility, Bitcoin remains the most valuable and influential cryptocurrency in the global digital asset market.
