I'm curious how people manage to actually cash out on these $100m+ heists, how do they convert that money to fiat without raising suspicion? People can barely get away without declaring $50,000, but these guys are going to suddenly become $500m richer and expect nobody to notice?
In this case it will be harder since the xems they stole has been tagged. It will he harder for them to put it in an exchange and withdraw it. In other cases where it is already bitcoin, they just have to use mixers to clean their coins and slowly turn it into fiat. Then they have to launder it again in order to spend the money freely.
