Bulgaria does look like a winner for electric costs based on what I just read there. I was curious about the costs in Romania, since I lived there for a few years (although not recently). About a decade ago Romania was ranked as the #3 country in the world for Hackers, right after the USA and China. Considering that it's a country with a mere ~21 million population I think that's pretty good evidence of the high technical savvy of the younger generations there. I know that crypto is quite popular there and you would easily find lots of people with some experience in it. The downside is that the country is extremely corrupt and the government is inept as well as being as crooked as a dog's hind leg. Electricity is quite cheap (industrial rates in particular), goods are accessible if you have the money to buy them, internet is fast, cheap and stable, and if you were in a city with a higher elevation (Brasov or Cluj-Napoca come to mind) the summer temperatures aren't that bad.
