Bitcoin (BTC) is more than just the first cryptocurrency—it’s the foundation of the entire crypto ecosystem. Launched in 2009 by the mysterious Satoshi Nakamoto, Bitcoin introduced the world to decentralized, peer-to-peer finance. With a fixed supply of 21 million coins, BTC is often seen as “digital gold,” a hedge against inflation and a store of value. Unlike fiat, it’s not controlled by any government or central bank. Over the years, Bitcoin has evolved from a fringe idea to a global asset class. Whether you’re a trader, investor, or just curious, understanding BTC is the first step into crypto.
