Interesting piece.
I think I'll stick with Proof of Stake. Current predictions speculate that electricity supply needed bitcoin miners would be equivalent to electricity supply used by countries.
That's definitely not good for the environment.
So for me, it's proof of stake. Delegated proof of stake to be exact. Why? Because it allows investors to protect their stake and allow experienced folks (witnesses) handle the technical aspects

I agree with you. My favorite is also delegated proof of stake.
