Is there any solution yet to preventing stolen cryptocurrency funds from being spent? Isn't the only solution to have a central database and require laws to require every transaction to be pre-checked to see if it's stolen funds or not?
And not only that, the centralized system will have to be constantly keeping track of wallet mixing to see where funds are being redirected to, attempted to being washed to?
There is absolutely no way of knowing if the money is good or bad. If you consider every mixed_cash as bad, you would be forced to assume that the entire cryptocurrency is bad bec of how the money flows.
