Market Cap measures the total USD-denominated value of a crypto asset's circulating supply, calculated by multiplying the total number of coins in existence by the current market price. It serves as the most widely referenced measure of an asset's overall size and market footprint relative to other assets in the ecosystem.
While straightforward to calculate, Market Cap has important interpretive limitations - it reflects the marginal price of the last transaction applied to the entire supply, meaning it can overstate the actual capital required to move or liquidate the market. A small number of transactions at elevated prices can produce a large market cap figure without representing genuine liquidity depth.
Tracked alongside Realized Cap, exchange reserve, and on-chain flow metrics, Market Cap serves as a foundational reference point for valuation frameworks such as MVRV - where the relationship between market cap and the aggregate cost basis of all holders provides a more nuanced view of whether the asset is overextended or undervalued relative to its on-chain economic reality.
