$BTC Bitcoin (BTC) is a decentralized digital currency that operates without a central authority or bank. Launched in 2009 by the pseudonymous Satoshi Nakamoto, it uses blockchain technology to securely record transactions on a public ledger. Bitcoin allows peer-to-peer transfers without intermediaries, making it popular for its transparency, low fees, and resistance to censorship. Its limited supply of 21 million coins adds to its value proposition as “digital gold.” Bitcoin has sparked global interest from investors, technologists, and financial institutions. Despite price volatility and regulatory challenges, it remains the most widely recognized and adopted cryptocurrency in the world today.
