Just an aside, you're definitely not going to launder $600 million through a strip club.
It has to be something high value, like real estate. To make a cash transaction, you'd probably want it to be in another country, one that accepts USD as a reserve currency but is not friendly with the United States. Of course in that scenario you're at the mercy of a hostile foreign government. Obviously, extensive bribes would be necessary. If you don't cover all your bases, your collaborators might end up dead/permanently imprisoned and you would be out of your money. In any event, it would not be a pretty transaction, and you'd be working with a lot of bad actors.
This would have been a much more interesting movie, btw.
