MVRV (market-value-to-realized-value) ratio is, as the name suggests, a ratio of an asset's market capitalization to its realized capitalization.
By comparing these two metrics, MVRV can be used to get a sense of when price is above or below "fair value", thereby helping to spot market tops and bottoms.
MVRV is calculated by dividing an asset's market cap by its realized cap.
