You need to ask about how many bitcoin wash trading compared to altcoins and you will find its rate less than altcoins and it is difference between good/high volums exhanges and unknown ones
Concerning Wash trading, this is just another one of those "things" about crypto that get discussed endlessly just because they are just evolving. Wash trading refers to bots buying and selling constantly on an exchange to make it appear like there is huge volume (Amount of Buys/ sells taking place). Stuff like this happens because the market participants in crypto don't really have actual information to judge a project with, like what have they delivered? What is the distribution, whether its a legitimate team...All that stuff doesn't matter.
People want hype and the assurance of a CEX listing with the illusion of trading. Thus the scammers opt for this tactic. This is just stuff copied from the traditional markets so nothing to see there.
Its just that there needs to be some kind of cap at how many products of the same type can launch and how anon can a team be. With the memecoins and rug-pulls, its as if there is no limit to the appetite for risky products..
These meme coins are probably used to make it appear like the volume is huge. No wonder they are listed on big exchanges despite how useless they are. Shibinu had created a not of them after it like the Floki but then it's the same thing yet listed on different exchanges.
If it increases the volume of the exchanges, they're rank high on the list of exchanges like on CMC. I guess it's thier way of promoting themselves too. I use to see Vindax and P2pB2B on top before binance bought the CMC. Now they are way 100.
