Trust is something between humans. If you cannot find an arrangement of checks and balances that gives people comfort that the "system" is not ripping them off there is no amount of cryptoaccounting that will solve it for you.
The very anonymity of the bitcoin founder(s?) shows this was never an honest-to-goodness project. Its not surprising then that crypto never solved any real economic problem. As in: making any economy a tiny bit healthier, more resilient, less unequal. Not a single one.
But had it stayed a failed financial reform project would have been one thing. It is heartbreaking to witness the amount of fraud, waste of resources and manipulation it unleashed. Its ongoing amoral adoption by the formal financial system as "yet another asset class offering diversification to our customers" is a fitting closure.
The chicken came home to roost.
