$BTC Bitcoin (BTC) is a decentralized digital currency, created in 2009 by Satoshi Nakamoto, operating on a peer-to-peer blockchain network. It enables secure, transparent transactions without intermediaries like banks. BTC’s supply is capped at 21 million coins, making it scarce and resistant to inflation. Miners validate transactions and earn rewards, though mining difficulty and energy use are concerns. Bitcoin’s price is volatile, driven by market demand, adoption, and macroeconomic factors. It’s used for payments, remittances, and as a store of value, often called "digital gold." Regulatory scrutiny varies globally, impacting its mainstream adoption. Despite challenges, BTC remains the leading cryptocurrency, shaping the future of finance.
