Sooner or later people are going to tire of the incessant ETC/ETH bullshit and jump on something else. Maybe Ardor?
I have thought about this as well. Soon the hype for ETH/ETC will be all over and their prices will start to decline. DAOs will be a thing of the past and thus people would move onto new and better things. In my opinion, I think that NXT/Ardor will get pumped too much after the release of the Ardor platform. But it may all end once the hype is over with this one too. Anyways, as long as NXT price goes up the more profitable will be for NXT holders when Ardor comes up.
