Fully Diluted Valuation (FDV) refers to the hypothetical market capitalization of a cryptocurrency if all of its total supply were in circulation, calculated using the current market price. The FDV is theoretical because adding more coins to the circulating supply could influence the price. Additionally, factors like tokenomics, emission schedules, or lock-up periods can delay the full release of a coin’s total supply into the market, meaning it may take a long time before the FDV becomes relevant.
