In my own idea, moving the mining companies can not be a good idea and it's just temporary solution, who knows what's going be happen in Kazakhstan during the next years? how stable is the government? maybe after one year Kazakhstan ban bitcoin mining too. Even if miners use renewable energy, the governments will still ban bitcoin mining, because do not agree with the privacy and availability of bitcoin, any government see this freedom can be dangerous for their banks and economic system, so they will try to fight against it. A big share of money they earn come from the tax they get from people and the money you invest in banks, by using bitcoin they will earn less tax, less investing on banks. So, they will fight against bitcoin by suspending mining companies.
