Market cap = Current price x Circulating supply

A measure of how much of a cryptocurrency was traded in the last 24 hours.

Indicator of liquidity. The higher the ratio, the more liquid the cryptocurrency is, which should make it easier for it to be bought/sold on an exchange close to its value.
Cryptocurrencies with a low ratio are less liquid and most likely present less stable markets.

Total supply = Total coins created - coins that have been burned (if any) It is comparable to outstanding shares in the stock market.

The best approximation of the maximum amount of coins that will exist in the forthcoming lifespan of the cryptocurrency, minus any coins that have been verifiably burned.

The amount of coins that are circulating in the market and are in public hands. It is analogous to the flowing shares in the stock market.
