It is about crypto market manipulations which was said on the article to have began since the first crypto exchange existed many years ago.
I am active on many exchanges and I see coins that are manipulated almost daily. The more the exchange list more coins, the more you will see more manipulations.
We knew all about that and it cannot be denied many market manipulations happen in many exchanges. The lower liquidity ones are easier to manipulate too.
Also most low marketcap coins are very easy to manipulate and they are the ones that the manipulators mostly visit. Those slightly high and high marketcap coins are still not completely resistant to manipulations but low marketcap coins are the riskiest.
Yes, even the top ones cannot skip the manipulation that can be done either by the whales of this market or the institutions that are trying to take the most of money from people that can easily be manipulated. And so, those traders that know that this is happening, they could just simply ride it and no need to complain because whoever is the smartest, the smart money goes to them.
