$BTC *Bitcoin (BTC)* is the first decentralized digital currency, created in 2009 by an anonymous figure known as *Satoshi Nakamoto*. It introduced a revolutionary concept—money without banks—allowing people to send and receive funds directly through a peer-to-peer network. Bitcoin operates on blockchain technology, a transparent and immutable public ledger that records all transactions. With a limited supply of 21 million coins, it is often seen as "digital gold" and a hedge against inflation. Over the years, Bitcoin has evolved from a niche tech experiment to a global financial asset, influencing economies, investment strategies, and the future of decentralized finance (DeFi).
