$BTC Bitcoin is the world's first and most popular cryptocurrency, created in 2009 by the mysterious Satoshi Nakamoto. It operates on a decentralized network based on blockchain technology, ensuring secure, transparent and immutable transactions without the need for intermediaries such as banks. Its supply is limited to 21 million coins, giving it a deflationary character. Bitcoin has become a digital investment asset, a globally accepted means of payment, and a store of value similar to gold. Despite its volatility, it has driven the decentralized finance revolution and cryptocurrency adoption.
