What is Bitcoin?
Bitcoin is a decentralized digital currency created by an anonymous person or group using the name Satoshi Nakamoto in 2008. It was the first cryptocurrency and remains the most valuable and widely adopted.
Unlike traditional currencies issued by governments (fiat money), Bitcoin operates on a peer-to-peer network without any central authority. Transactions are verified by network nodes through cryptography and recorded on a public distributed ledger called the blockchain.
Bitcoin is often called "digital gold" because of its limited supply — only 21 million bitcoins will ever exist. This scarcity, combined with its decentralized nature, makes it a store of value and a hedge against inflation.
