$BTC $BTC BTC is the ticker symbol for Bitcoin, the first and most well-known cryptocurrency. It was created in 2009 by an anonymous individual or group under the pseudonym Satoshi Nakamoto. Bitcoin operates on a decentralized network called blockchain, which is a distributed ledger that records all transactions transparently and securely.
