What if it's not? What I'm suggesting is that cryptocurrencies may be insect-eating tree rats scurrying in the dense brush. Not prospering. Not expanding. Just surviving. Surviving during the reign of the dinosaurs.  Surviving for many millions of years in the shadow of reptiles until an opportunity presents itself. If that opportunity presents itself, the tree rats and their descendants can take over the whole game. If not, then they occupy their little niche in the shadows forever. What you're suggesting seems to be that the tree rats can have a solid future in their niche. But I'm not seeing it. Not when the dinosaurs are occupying all the skies and land and seas.
