Just saw this post, I guess I am incorrect then. I'm still a bit confused about why a platform such as Coinmarketcap (which isn't even an exchange themselves) would advertise false prices on certain coins?
The reason because they are the most visited crypto market cap rankings website that's why there's an advantage for them to do that. We don't know on why they do that.
The articles are about the faked volume on exchanges that are listed on Coinmarketcap, which isn't really their problem (Coinmarketcap is here to provide you with a list of stuff), and if the exchanges are reporting that volume to CMC, what can they do about it?
This is more on the technical side.
It'll be a problem if they accepted payments in order to fake volume.
As I've mentioned, we don't know.
