$BTC Bitcoin is a decentralized digital currency, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks. Transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins. It can be used for online purchases, investments, and as a store of value. Its price is highly volatile, influenced by factors like market demand, regulatory news, and macroeconomic trends.$BNB
