Fucking thank you. I get just as many downvotes when I suggest this but it's very obviously the right thing to do.

PoW doesn't scale. It eats up power needlessly and we're only stuck on it because the original BTC was a PoW cryptocoin. Simply banning trading of PoW coins would do mounds of good - the crypto community would be better streamlined to move toward PoS coins of the future and environmentalists wouldn't have to waste their resources lobbying to ban BTC anymore.
