Where can you buy it?
Bitcoin exchanges. Bitcoins can be purchased through exchange operators dedicated to cryptocurrencies, as well as traditional operators such as the Chicago Mercantile Exchange (CME) and the Swissquote Bank, among others.
In those public exchanges, bitcoin is traded under the XBT and BTC symbols. Bitcoin Cash (BCH) is another cryptocurrency with its own price.
CME's Bitcoin Reference Rate (BCC) is a spot price index used by CME and is based on the daily bitcoin price on specialised exchanges such as Bitstamp, GDAX, itBit and Kraken.
