1% ? I call big bullshit on that!
Everyone that i know thinks about it or mine themselfs and that includes older people as well. Non tehnical.. On top of that since bitcoin rush i get power downs all the time in my city and i know that mine is not the only city that goes trough this
But anyway. Calling bitcoin green or not green is just stupid. Everything that consumes electricity is neutral. Power production on the other hand can be green or not. I think that media should talk more about how we provide power instead of talking about what we do with it
