$BTC
Bitcoin (BTC) is a cryptocurrency (a virtual currency) designed to act as money and a form of payment outside the control of any one person, group, or entity. This removes the need for trusted third-party involvement (e.g., a mint or bank) in financial transactions.If you don't want to mine Bitcoin, you can buy it using a cryptocurrency exchange. Most people will be unable to purchase an entire BTC because of its price, but you can buy portions of one BTC on these exchanges in fiat currency, such as U.S. dollars.
