$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by an anonymous figure known as Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing peer-to-peer transactions without the need for intermediaries like banks. Bitcoin's value lies in its limited supply—only 21 million coins will ever exist—making it a hedge against inflation for many investors. Over the years, it has grown from a niche digital asset to a globally recognized store of value. Despite market volatility, Bitcoin continues to lead the crypto space, shaping the future of decentralized finance and inspiring innovation across digital economies.
