It's a U.S. organization that goes after financial crime world-wide. I just gave it as an example. Point being, many types of money moving require careful laundering to prevent traces for financial or other prosecution. It's why most crooks focus on trying to steal straight cash if they're here in U.S.. A guy with an easily-moved, unregulated, semi-anonymous stash of millions is a much easier target and the government might not be able to help him. So, more risk than usual and varies depending on his location.
