For a long time, I did not trust the evaluation and display of CMC. The number of fake volumes is huge. The figures here are not realistic. If in the top 10, I think of Binance, okex, houbi, ... but I don't see it here lol.
I think you're wrong judging coinmarketcap site displaying with fake volumes in the cryptocurrency world. CMC site has the only trusted company that monitors the real volume of each coin. Including the ranks of every coin and exchange.
