#33In a hypothetical, if the two did not breach Bitfinex servers (unauthorized access to others systems) but instead managed to "guess" the private key to the Bitfinex wallet and transfer the funds, would this also be a crime? Would this be treated the same way?

#35I ask this every so often during threads regarding stolen cryptocurrency: 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 wh…

If a bank accidentally leaves a sack of cash on the sidewalk and you take it, it is not yours. Plus they didn't declare any of the money and instead laundered it through a bunch of sham companies and fraudulent users on crypto exchanges.
