Bitcoin, also known as BTC, is a decentralized digital currency that was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. It is the first cryptocurrency and operates without a central authority or government.Bitcoin transactions are recorded on a public ledger called the blockchain, which is maintained by a network of computers known as miners. These miners use powerful computers to solve complex mathematical puzzles that validate and secure transactions on the network.One of the key features of Bitcoin is its limited supply, with only 21 million coins ever to be mined. This scarcity has contributed to its value increasing over time. Bitcoin can be used to purchase goods and services online, as well as for investment purposes.Bitcoin has faced criticism for its volatility, potential for illegal activities, and environmental impact due to the energy-intensive mining process. Despite these challenges, Bitcoin remains a popular and widely used cryptocurrency in the global market.
