Just came across this, published last month, but don't recall seeing anything like it on the forum, so just sharing.
Original article by 911 Metallurgist, it's got the rates for some other crypto too but I'm just going to share the one for Bitcoin:
Cost to mine 1 Bitcoin in every country.
I knew Asia was expensive, but not THAT expensive. Also, I think this is the cost of grid electricity. I know in my part of the world, for example, some miners want to experiment with natural gas generators. Far, far cheaper, no one would plug into the grid!
Kuwait, though!
I'm surprised Nigeria doesn't seem to be on the list of counties that cost the least to mine bitcoin. Considering how much energy Nigeria as a country has. But it could also be that there aren't so many people that mine bitcoin like the other countries.
