$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by an anonymous person or group under the name Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without the need for intermediaries like banks. Bitcoin's limited supply of 21 million coins contributes to its scarcity and value proposition as "digital gold." It has gained global attention as both a store of value and a speculative asset. BTC's price is highly volatile, influenced by market demand, macroeconomic trends, and investor sentiment. It remains a key driver in the development of the broader crypto ecosystem.
