$BTC
Bitcoin (BTC), the first and most well-known cryptocurrency, was introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins and its role as a store of value. Despite price volatility, BTC has gained widespread adoption among investors, institutions, and even governments. As the crypto space evolves, Bitcoin continues to shape the future of finance and challenge traditional economic systems.
