Without a doubt bitcoin mining got way ahead of itself. But the price of video cards is finally going back down. There is a lot of competition in the mining space and a lot of risk. If you aren't willing to relocate repeatedly, you could have your power shut off. A lot of areas absolutely hate the idea of bitcoin mining for some reason and governments don't appreciate it when they are subsidizing power and bitcoin miners take advantage of that. I think more bitcoin miners need to be in places that want heat. That would at least do something.
