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.
In many point, yes CMC has been beneficial frrom all of us, it helps us investors/users to identify the market cap, circulating supply which we can help to assess a certain coin. But we also know that they do have a lot of shitcoins too that are still listed there as well as shit exchange, well I really do hope they will do something about it.
