What Is Market Capitalization?
A crypto market cap calculator computes a cryptocurrency's total market capitalization by multiplying its current price by the circulating supply. It also calculates fully diluted valuation (FDV) using the maximum token supply. The most powerful feature is "what if" comparison: see what your coin's price would be if it had the same market cap as another project. This helps you evaluate whether a coin is under- or overvalued relative to competitors. All calculations happen instantly in your browser with no data shared externally.
