Nothing new as this happened all the time. Fake volume, fake price, bots and so on, manipulation at its fullest potential.Did you actually believe that exchanges are having that amount of volume per 24 hours ? Think again mate, nothing is what it seems and nothing will change anytime soon as the party won't stop. Be glad that pump and dumps don't happen like they did before or at least it happens in low ranked coins which is the good part.
I know that I have heard of a lot of exchanges manipulating the cryptocurrency market, but I have not really paid attention to them as I don’t think that I am using an exchange that is doing such a thing, the exchange that I am presently using which is binance has very high users that is using their platform on a daily basis, and I really don’t think there should be any reason why they should manipulate prices gain.
They might have done it in the past, maybe when they were first released in order to get some attractions, but now that they have lots of real users, they would not be crazy enough to still continue to engage in this shady activities and I think most of their volume can be very reliable, which is why I believe the data that I see on binance exchange even more than coinmarketcap data.
