I do agree that PoW in a big scale is stupid. Those resources could be used to host cloud services, compute big important problems, etc... PoW by now is basica

I do agree that PoW in a big scale is stupid. Those resources could be used to host cloud services, compute big important problems, etc... PoW by now is basically PoS with extra steps But, even for the environment, I can't take people thinking it is a good idea govs using PoW, or standard exchange problems, to ban All crypto-currencies. While creating their own fake digital coin PoS is also not ideal since it keeps promoting the same rules has the old system. Who has more money will keep having more independent if their producing something useful So I think we still need something new, and someone smart to come up with it Something that works for big groups, like a combination of localized PoW plus global PoS with PoT. Proof of trust, like most systems work
