$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is limited to 21 million coins, which contributes to its scarcity and store-of-value appeal. Often referred to as "digital gold," BTC is used for investment, transactions, and as a hedge against inflation. Its price is highly volatile, influenced by market demand, regulation, and macroeconomic trends. As adoption grows, Bitcoin continues to play a central role in shaping the future of digital finance.
