$ENA Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized peer-to-peer network using blockchain technology, which ensures transparency and security without the need for a central authority. BTC is often seen as “digital gold” due to its limited supply of 21 million coins, making it a hedge against inflation. It allows users to send and receive money globally, quickly, and with low fees. Bitcoin has influenced the creation of thousands of other cryptocurrencies and continues to play a central role in the crypto ecosystem.
