They are already, look at the Bitcoin Cash pump. But just like spamming the Bitcoin network is a futile and short lived strategy, the pump money on BCash is also short lived and futile. Sooner or later Roger Ver and whoever else is orchestrating this attack will run out of money and things will go back to normal, because there is no fucking way that out of nowhere all this transaction growth is organic and not part of an altcoin pump and dump scheme.
I think you're wrong. I know people that are noobies to crypto who are buying bcash because they think bitcoin is too expensive. It's easy to imagine that this is the case all over the world.
