$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without intermediaries like banks. Bitcoin's limited supply of 21 million coins makes it a deflationary asset, often referred to as "digital gold." It has gained widespread adoption as both an investment vehicle and a means of payment. Bitcoin's price is highly volatile, influenced by market demand, regulatory news, and macroeconomic trends. Despite challenges, Bitcoin continues to drive innovation in the financial sector and is a cornerstone of the broader crypto ecosystem.
