I think Canada is the best alternative other than China.
Low rate, natural cooling etc.
I think mining farms will be more profitable if they are located on Africa and India because the electricity rate is more cheaper than other countries I think.But im not an expert in the mining and it's profits,I will looking forward for the suggestions of this thread to know more about best place to build mining farms.
it is a lot more profitable to mine bitcoin in India not just because of the electricity cost but also because bitcoin price has been higher over there for a long time now. and as long as the problems that cause this higher bitcoin price persist, things will remain this way.
there is a similar situation in Zimbabwe. and in fact there are people mining bitcoin there, and then using the coins they mine to buy food oversees and then import that food into their country and sell it and make a good profit this way.
