I think its time to ban new altcoins from coming in, there should be a limit on how many altcoins there should be per year
so that people can actually profit from investing in altcoin.
Banning altcoin is not really a great way to the coming of new one. Maybe they could be given some limit, just what you have said but not really control from having a new one. It is their own strategy or decisions to earn and is none of our business.
