Bitcoin (BTC) is a decentralized digital currency that operates without a central authority or banks. It was introduced in 2009 by an anonymous figure known as Satoshi Nakamoto. Transactions are verified by a network of nodes through cryptography and recorded on a public ledger called the blockchain. Bitcoin offers an alternative to traditional fiat currencies, with a fixed supply capped at 21 million coins, making it resistant to inflation. Often referred to as “digital gold,” BTC is used both as a store of value and a medium of exchange. Its influence continues to grow across financial and technological landscapes worldwide.
