How the hell do you know? You've just admitted that you don't actually know how PoS and PoW work. You've repeatedly refused to "do your homework" by researching what's known about these things. And yet you have repeatedly been rude to other people who have done their homework, and have informed opinions, unlike you. Just shut up and stop talking about blockchains. You're an entitled internet nobody.
I have regrets about calling you a "nobody". I was annoyed, but that's going too far, and I apologise for saying that. Almost no one deserves that level of vitriol, especially if at worst they're just being annoying. And I think I get annoyed too quickly.
