I like it, literally revolutionary, to my eyes BTC owes more to PoW than Blockchain. You start seeing it everywhere, related to Taleb's skin in the game concept, or costly signaling in zoology.
Probably 0 if I had a choice. But is global warming a problem that is exclusive to bitcoin? Or does bitcoin highlight and accelerate an existing problem that is already a problem through other means, like car/plane emissions and AI datacenters.
Whatever solution we come up with, will work against all sources of warming or environmental damage. Although if one of those measures is banning Bitcoin mining, I wouldn't complain about it.
