Bitcoin

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, allowing users to send and receive payments without the need for a central authority, such as a bank or government. Transactions are recorded on a public ledger called the blockchain, which ensures transparency and security. Bitcoin uses cryptographic techniques to secure transactions and control the creation of new units, with a maximum supply capped at 21 million bitcoins. It is often referred to as a cryptocurrency because it relies on cryptographic principles for verification and security. Bitcoin has gained popularity as an investment and a means of transferring value internationally, often seen as an alternative to traditional currencies and banking systems.
