Bitcoin ($BTC ) is the world’s first decentralized digital currency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a peer-to-peer network without a central authority, relying on blockchain technology to ensure transparency and security. Bitcoin has a fixed supply of 21 million coins, making it resistant to inflation. It enables borderless transactions and serves as both a medium of exchange and a store of value, often referred to as “digital gold.” Despite its volatility, Bitcoin has gained widespread adoption among investors, institutions, and individuals seeking alternatives to traditional financial systems and fiat currencies.
