Market capitalization = Current price x Circulating supply.
Cryptocurrencies are bought and sold at different rates, and seeing how many transactions take place in a coin can give you an idea of how its popularity is changing. Volume simply refers to the number of transactions of a cryptocurrency that have occurred in the last 24 hours.
Fully Diluted Market Cap (FDMC) = Price x Maximum Offer
Cryptocurrency is “mined” by performing complex calculations, which lead to the generation of “coins”. Of these, only a certain number will be in circulation, in the hands of the public to be bought and sold. This is the circulating supply, similar to shares that circulate in the stock market.
Some cryptocurrencies, including Bitcoin, have a fixed upper limit on the number of coins that can be mined. This is done on purpose: for example, only 21 million Bitcoins will be mined. Litecoin also has a maximum supply of 84 million. On the other hand, some cryptocurrencies like Dogecoin and Litecoin do not have an upper limit.
Total supply is simply all the coins that have already been mined from the maximum supply, minus any coins that have been burned. If you are familiar with the stock market, you can think of it as outstanding shares.
