Search intent

This guide explains crypto market cap as a measurement, not as a guarantee of liquidity or project quality.

Formula

Crypto market cap is commonly calculated as current reference price multiplied by circulating supply. If a token trades at $10 and has 100 million units in circulation, the reference market cap is $1 billion.

What it can show

Market cap helps compare the relative size of crypto assets. It is useful next to 24h volume, circulating supply, and price change, because price alone does not show how large an asset is.

What it cannot show

Market cap is not the amount of cash in the asset and does not mean all holders could sell at the displayed price. Liquidity, unlocks, exchange access, and order-book depth matter.
