MVRV Z-Score is a metric that compares the market value of a cryptocurrency (in this case, Ethereum) to its realized value. The Market Value (MV) represents the current market capitalization of Ethereum, while the Realized Value (RV) is the total value of all ETH coins that have been transacted on the blockchain, weighted by the price at which they were moved. The MVRV Z-Score is calculated by subtracting the realized value from the market value and then dividing the result by the standard deviation of the market value.
