The most annoying part about these crypto exchanges is their ranks on rating websites e.g coinmarketcap, I wonder how this website get so blind and over look the fake volumes and watch trades, they need to be exposed
This is true, Coinmarketcap isn't really checking if the volumes are correct. Maybe it is programmed on that way for faster listing, but hopefully their devs will fix this kind of mess.
There may be errors in installing the system or the system takes time to update from the real market. This is a fatal mistake made by Coinmarketcap even though Coinmarketcap has been around for a very long time.
