I think The previous years are much more
fair to most people, but there is no way back now. Even if we wanted, the big-scale players in the mining race would not allow it.
But I still do not think it means that China has bitcoin in its grasp, more like if they have some kind of unfair advantage over the whole world, for now.
I agree on the idea that mining should not be so centralized, as it is now with asic devices.
