Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It introduced a revolutionary concept: a decentralized, peer-to-peer digital currency that doesn't rely on any government or central bank. Bitcoin transactions are recorded on a public ledger called the blockchain, which is maintained by a global network of computers (miners). These miners validate transactions and secure the network through a process called Proof of Work.
Over the years, Bitcoin has evolved from an experimental digital asset to a mainstream store of value, often referred to as "digital gold." Its fixed supply of 21 million coins makes it resistant to inflation, unlike fiat currencies. Bitcoin is widely used for investment, cross-border payments, and as a hedge against economic instability. Its adoption by institutions, countries, and even public companies signals its growing importance in the global financial system.
