I have thought deeply (I was AnonyMint) about the possible designs for decentralized consensus, as well the various strategies for anonymity that are plausible.
Then you probably shouldn't be taken seriously.
You were the guy who was claiming all kinds of doom scenearios with
people losing their houses and ending up in jail just for using
Bitcoins, and that massive bitcoin thefts would lead to transaction
"clawbacks". So far we haven't seen a single case of any of this
nonsense.
I agree you should leave cryptocurrency. Your pessimism isn't
adding anything of value to the community, yourself, or anyone else.
