I think personally that proof of stake and proof of work both don’t matter in the end.
I believe that all cryptocurrencies are at their heart scams.
Proof of stake doesn’t change this dynamic.
As I see it, cryptocurrencies doesn’t actually solve any real, significant problems we face as a (global) society.
And to pick one important thing: they exclusively enable crypolocker randsomeware, and we know their devastating impact.
Dollars are abused too, but the dollar gives so much back, our societies are based on it.
I see no benefit to society of cryptocurrencies and I would really like to see them go.
Nothing good has come from them. Zero.
