I hope the rest of world follows. There is nothing more volatile than a decentralised crypto currency. The amount of people making a profit from it is less than 5% and energy consumption is beyond acceptable. Crypto as a tech to serve something different is totally fine of course.
You probably live in the first world and had never to worry about inflation or politicians/bureaucrats just straight destroying the fiat currency and your wealth in the process. That's why crypto sounds so "wasteful" to you. BTW, if we give the government the power to judge what is a waste of energy and what's not, I can assure you life would be 100% more miserable, to everyone.
Crypto *is* volatile and wasteful compared to any of those.
