$BTC Bitcoin ($BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to ensure transparency and security. Unlike traditional currencies, Bitcoin is not controlled by any government or central authority, making it a popular choice for those seeking financial independence. With a capped supply of 21 million coins, Bitcoin is often referred to as "digital gold" due to its scarcity and role as a store of value. Its price is highly volatile, influenced by market demand, regulations, and macroeconomic trends.
