Evrywhere i read mining farm are open in cold country example Estonia but in uk is not good idea.
Hi,
There is a really cheap solution to keep the hardware cool ( Really big extractor fans combined with some well placed air ducts ) . The temperature of the country is not really an issue.
It's true that in Iceland and Estonia electricity is cheaper .. but if the farm is built abroad it creates additional cost ( Security, personal permanently on site etc . ) .
The previous farms that I built can be managed off-site ( They require cleaning once every few weeks .. + intervention in case of some small hardware failure , but this does not happen very often )
