A lot of mining seems to be moving to Iceland, which is really cold (therefore miners don’t need to waste money trying to cool their machines) and has plenty of cheap renewable energy and good internet connection : http://uk.businessinsider.com/photos-iceland-bitcoin-ethereum-mine-genesis-mining-cloud-2016-6/?IR=T/#the-company-had-early-mines-in-bosnia-and-china-and-most-of-its-operations-are-now-based-in-iceland-3

This has already been happening, and I think more and more mining will go to Iceland as a result of China’s decision.
