0.1% percent is pretty insignificant, it is 1/1000 of the world electric energy production, and that contributes only around 30% to total world C02 production.

0.1% percent is pretty insignificant, it is 1/1000 of the world electric energy production, and that contributes only around 30% to total world C02 production. Blaming and cancelling insignificant activities leads nowhere. And it's absurd, considering the main CO2 contributors are elsewhere - it is the transport and power plants which need this attention. If we are talking about affecting CO2 production via electric energy policies, more just way (and more effective way) to introduce "CO2 sanctions" on various activities is to factor the damage in the energy price. That way everybody feels the pain proportionally, not just few random scapegoats like BTC. I agree that price does not need to be the same for everyone. Maybe BTC activities should pay much more for electric energy than a normal (non-BTC oriented) household does.
