$BTC Bitcoin (BTC) is a decentralized digital currency that operates on a peer-to-peer network, allowing users to send and receive payments without the need for intermediaries like banks. It was created by an anonymous figure or group known as Satoshi Nakamoto in 2008 and released as open-source software in 2009. Bitcoin uses blockchain technology, a distributed ledger that records transactions across many computers to ensure transparency and security. BTC has gained significant attention over the years due to its potential as an alternative investment, a store of value, and a hedge against inflation. Its volatility, however, remains a challenge for many investors.
