Also known as market cap, this is the total value of a cryptocurrency's circulating supply.
An important metric, the market capitalization or market cap, is the total value of a cryptocurrency's circulating supply, calculated by multiplying it with the price per unit.
So if a cryptocurrency has a circulating supply of 1 million coins/tokens and it is trading at $5 per coin/token, the market capitalization would be: 1 million x $5 = $5 million.
The important point to remember here is that the market cap metric utilizes circulating supply as opposed to total or max supply.
