$BTC Bitcoin (BTC) is the original and most well-known cryptocurrency, created in 2009 by the anonymous figure Satoshi Nakamoto. It operates on a decentralized network using blockchain technology, meaning transactions are recorded transparently and securely without the need for intermediaries like banks. Bitcoin is often viewed as “digital gold” due to its scarcity (only 21 million coins will ever exist) and its potential as a hedge against inflation. Over the years, it has evolved from a niche digital asset to a global financial phenomenon, attracting investors, traders, and institutions alike.
