$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by the mysterious Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without the need for banks or intermediaries. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins, making it a hedge against inflation. Investors use BTC for both long-term holding and short-term trading. Its price is highly volatile, influenced by global events, regulations, and market sentiment. As adoption grows, Bitcoin continues to shape the future of finance and challenge traditional monetary systems.
