Bitcoin cash and all other altcoins you mentioned are just some useless coins. The hash rate of Bitcoin cash (which has been the most successful fork of bitcoin) is only 0.4% of hash rate of bitcoin.
We don't need any more shitcoins and if there's any other fork of bitcoin like bch, bsv, etc. most of the people will probably sell them just to get rid of them.
I try to rule it to the fact that, people now know better. Before hand, a lot of people look towards these altcoins to be the next and most of all, when it’s linked or have some ties related to Bitcoin. They try to confer on them some of the rep Bitcoin have belt a short period of its existence. People who can’t differentiate jump at it while those that can and have ideas as to how this works just stay off it. Developers know this now and have shifted their focus elsewhere with memecoins and whatever name they could give it.
