$BTC
Bitcoin ($BTC) is the first decentralized cryptocurrency, launched in 2009 by Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology, allowing secure, transparent, and irreversible transactions without central authority. Bitcoin has a capped supply of 21 million coins, making it deflationary and often viewed as “digital gold.” It is mined using proof-of-work, where miners validate transactions and secure the network. $BTC is widely used for payments, investments, and as a hedge against inflation. Its price is volatile, influenced by demand, regulations, and macroeconomic factors. Bitcoin has sparked a global movement toward decentralized finance and digital assets.
