Bitcoin mining is always looking for the cheapest energy available anywhere in the world. It makes no difference if you are mining in America or Asia, you just need the cheapest energy.
Hydroelectricity is the cheapest (or of the cheapest) energy sources available.
All this fake news and misinformation about bitcoin mining is sad.
Bitcoin mining uses as much electricity as Christmas lights decorations.
http://www.coindaily.co/christmas-decorations-consume-as-much-electricity-as-bitcoin-mining/I guess that's true with only mining rig that is used but, how about if you are using multiple mining rig to mine Bitcoin? Is it also the same power usage as Christmas decorations? I know I am not into mining but I was just curious about it and how much is the power consumption on every mining rig or is there any way to lessen it's energy consumption without using hydroelectricity.
