Crypto market capitalization or "crypto market cap" for short is a widely used metric that is commonly used to compare the relative size of different cryptocurrencies. On CoinCodex, market cap is the default metric by which we rank cryptocurrencies on our frontpage. We also track the total cryptocurrency market cap by adding together the market cap of all the cryptocurrencies listed on CoinCodex. The total market cap provides an estimate on whether the cryptocurrency market as a whole is growing or declining.
