$BTC Bitcoin (BTC), the first and most well-known cryptocurrency, has revolutionized the financial world since its creation in 2009 by the pseudonymous Satoshi Nakamoto. Operating on a decentralized blockchain network, Bitcoin allows peer-to-peer transactions without intermediaries like banks. It is powered by a consensus mechanism called Proof of Work, ensuring security and transparency.

Bitcoin is often seen as "digital gold" due to its limited supply of 21 million coins, making it a popular store of value. Its volatility has made it attractive to traders and investors, while its potential to disrupt traditional financial systems has drawn both praise and criticism. Over the years, Bitcoin has gained widespread adoption, influencing financial technology and global economies.
