Indeed, This is a funny thing when someone will refer cmc for depend trading volume and considering projects liquidity. You able to focused only bibox exchange but you know there are many exchanges volumes are fake. Latoken,Vindex,p2pb2b,Exrates i would to told that its a 100% wash trading. Bibox is better from those terrible exchanges.
I don't think we can completely blame Coinmarketcap, because it only displays data from an exchange, I think if there is a fake volume or anything like that we have to find out for ourselves.
