This is the maximum number of coins that will exist for a token or cryptocurrency. If there is a max supply defined, no more coins can be created. ‘Burned’ coins are part of this supply, so therefore it is always larger than or equal to the total supply. For Bitcoin, the maximum is set to 21 million.
