$BTC Bitcoin (BTC) is a digital currency launched in 2009 by a mysterious figure known as Satoshi Nakamoto. It was designed to let people transfer money directly without banks or middlemen. Bitcoin runs on blockchain, a secure online ledger that records every transaction. Only 21 million bitcoins will ever exist, which makes it rare and valuable. Many investors buy Bitcoin as a way to protect their wealth from inflation. It can also be used to make purchases, though its price often rises and falls sharply.
