Market capitalization of a coin is calculated by multiplying the current price in USD or EUR of a single unit of coin by the current circulating supply of that coin available for sale or purchase on public exchanges.

Ex: If the price of BTC is currently $20,000 and there are 50,000 BTC available on public exchanges, then the Market Cap of BTC is $1,000,000,000.

Volume of a coin is the total spot trading volume reported by all exchanges over the past 24 hours multiplied by the value of an individual unit of that coin.

Circulating supply is the approximate number of units of a coin that are currently circulating in the market in the hands of the general public.
