It is a complex problem, you don't have to blame just Coinmarketcap, because devs are also responsible for what steps they are doing to develop the project. I will never go to trade to exchange if i won't check all info about it. So, it is easy. But, yes, fake volumes problem is frustrating, hope it will end soon.
the problem of fake volume has been an old problem, I think CZ can overcome that easily, maybe the data will be sourced from Binance, which we should be aware of is indeed a new project, Coinmarketcap must be firm with new projects and not as easy as putting the project on the list !, C'mon, Coinmarketcap must make a difference
