$BTC Bitcoin ($BTC) is the first and most prominent cryptocurrency, created in 2009 by an anonymous entity, Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling secure, peer-to-peer transactions without intermediaries. With a capped supply of 21 million coins, Bitcoin is considered a deflationary asset. Its volatility has attracted traders and investors seeking high returns, while its use as a store of value has earned it the nickname "digital gold." Bitcoin is widely accepted for payments and continues to be a key player in the cryptocurrency space, though it faces regulatory scrutiny and price fluctuations.
