Bitcoin (BTC) is the first and most popular decentralized digital currency, launched in 2009 by a person or group under the pseudonym "Satoshi Nakamoto". It is based on blockchain technology, which is a transparent and immutable digital ledger used to document transactions without the need for a central intermediary such as banks. Bitcoin is mined using computers to solve complex equations, which secures the network and issues new coins. Bitcoin is characterized by scarcity, with a maximum total supply of only 21 million coins. It is used as a means of payment, a store of value, and a tool to hedge against inflation, but it faces challenges such as price volatility and government regulations. #BTC
