$BTC Bitcoin is a decentralized digital currency created in 2024 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 finite, with a maximum supply capped at 21 million coins, making it deflationary. It can be used for online purchases, investments, or as a store of value. Its price is highly volatile, influenced by demand, adoption, and regulatory developments. Bitcoin has sparked the growth of thousands of other cryptocurrencies.
