That's their loss. I mean, China. The miners will simply move somewhere else and we are seeing it happening now.

The power grid operators don't care if you are looking for aliens, solving optical goloumb rulers, finding a cure for cancer, calculating large prime numbers, growing plants indoors or mining for any coins. If you use power and pay for it, then you should be okay, doesn't matter what you do.

Miners will simply migrate (or at least the equipment does) to wherever it makes sense for them, usually that means where it's cheaper.
