$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 a supply of 21 million coins, which contributes to its scarcity and value proposition as "digital gold." It allows for borderless transactions without the need for intermediaries like banks. Over the years, BTC has evolved from a niche digital experiment into a mainstream asset, attracting investors, institutions, and governments. Its price is volatile, but it remains a leading force in the crypto industry.
