$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, introduced in 2009 by an anonymous figure known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which records all transactions transparently and securely. Unlike traditional currencies, Bitcoin is not controlled by any central authority, making it resistant to inflation and government manipulation. Its limited supply of 21 million coins adds to its scarcity and value proposition, often leading to its comparison with digital gold. Bitcoin has evolved from a niche digital experiment to a mainstream financial asset, influencing global markets and attracting investors, institutions, and governments alike. Its price is highly volatile, driven by market demand, macroeconomic trends, and regulatory news.
