$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to record transactions transparently and securely. Bitcoin is limited to 21 million coins, making it deflationary by design. It is often viewed as "digital gold" due to its store-of-value properties. BTC can be used for payments, investment, and as a hedge against inflation. Its value is highly volatile, influenced by market sentiment, macroeconomic trends, and regulatory developments. Bitcoin remains a foundational asset in the evolving digital economy and crypto ecosystem.
