Yeah, this is a John Steele topic, for sure. The answer to the question is that according to the environmentalist priesthood, is that both of these things are causing global warming. Take time to scratch your head on that one:

     There are so many billions of porn viewings, that any savings by computer dematerialisation has gone, well up in a puff of smoke.
Bitcoin mining uses up even more energy than porn; if Bitcoin was a country it would rank 61st in terms of energy consumption, and is set to gobble up even more electricity. I heard one Greenie on the radio say something along the lines that given mining trends, Bitcoin would chew up all of the world’s electricity in a few years. sheer nonsense, of course.

     My God, when will this environmentalist nonsense end? I don’t intend to defend porn, but the same argument could be made about almost everything, computer use, guns, car driving, guns, cooking, guns, you name it, even guns. The environmentalist wants a world where you and I die out, and they get to live in caves…yeah, the caves that the rich consumers leave behind. After all, it would not be ecologically sound to waste such resources.
