I can offer you colocation in about a month cheaper than that including administration - I am JUST outside of germany and pay.... 6.5 cents + VAT. During the day - night is cheaper

And we have a carbon tax coming in soon, which will boost coal and gas fired power costs nicely. No nuclear power here.
That is the next problem. Germany is currently phasing out all nuclear power plants, so energy costs will rise even more in the next few years. My guess is that next year bitcoin mining won't pay out anymore in germany.
