$BTC Bitcoin (BTC) is the world's first and most widely recognized cryptocurrency, launched in 2009 by the pseudonymous creator, Satoshi Nakamoto. It operates on a decentralized blockchain network, using a proof-of-work consensus mechanism where miners validate transactions and secure the network. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins, making it a hedge against inflation and traditional financial systems. Over the years, Bitcoin has gained mainstream adoption, with institutional investments, legal recognition in some countries, and growing acceptance as a payment method. Despite its volatility, Bitcoin continues to shape the future of finance, challenging centralized banking and offering an alternative store of value.
