Bitcoin

Bitcoin is a decentralized digital currency, introduced in 2009 by an individual or group of individuals using the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without the need for a central authority or intermediary, such as a bank. Transactions are recorded on a public ledger called the blockchain, which ensures transparency and security. Bitcoin can be used for a variety of purposes, including online purchases, investment, and as a store of value. Its supply is limited to 21 million coins, which is programmed into its protocol, making it distinct from traditional fiat currencies that can be printed in unlimited quantities. Bitcoin is often referred to as the first cryptocurrency and has paved the way for numerous other digital currencies in the market.
