1. | concept
Total number of coins or tokens in circulation or actively traded in a reasonable period of time.
There are currently over 17,000,000 BCH that have been mined, but due to some being lost over time there are fewer in circulation. Coins can be lost when the sole controller of a private key dies, the private key is lost or destroyed, or money is sent to an incorrect address. It is impossible to know exactly how many coins of a currency have been lost. In a decentralized system we can only know the total coins that have been mined/created, the eventual max supply, and how much is being moved over periods of time
