Total number of a coin/token available, calculated by taking the circulating supply and adding the additional amount of the asset that has been mined or created, but currently unavailable or locked up.
ICOs often reserve a percentage of the total supply for the team, to be locked up and divested over a number of years. If an ICO reserves 50% of a token for this purpose, and releases 50% as the circulating supply, then the total supply will equal twice that of the circulating supply. If more can be mined in the future then the Total Supply will not be equal to the Maximum Supply.
