I'd tap the Einundzwanzig community; I'm pretty ignorant of the state of things over there. But my 10,000ft view (er, 3,333m?) is that electricity prices are just too high across Europe for home mining to make much sense.

Here in Illinois I'm on real-time pricing and have subsidized, cheap nuclear power. My overnight rates (especially in the winter) are ridiculously cheap--even negative sometimes! And I have somewhat expensive methane furnace heating costs (easily ~$200/mo in the winter), so the math for me to shift my heat generation to mining is incredibly favorable.
