Your power DROPS after a certain quota? Insanity! Mine is 0.14, then 0.17, then .35, then .assrapage, and I always get to the final tier.
You luck US guys with your cheap power. In Europe we pay $0.20 per kwh
in taxes! And then the actual price of the power on top of that.
The EU increasing tier power always has me wondering how you can profitably mine with anything over there?
