You are just speculating. Tell me why you think that? It was clear they were doing everything they could to keep it off the casinos radar so the play would go as long as possible(big deal, that's just commonsense). This happen in a short period of time so it stands to reason they would have accumulated lots of cash in that short period of time. What are they going to do with all that cash? I have a feeling they were traveling back to split it up and regroup. Each person would be reasonable for declaring their winnings come tax time. You can't just suddenly go put a bunch of cash in the bank and transfer it all around. The banks can ban you and your account, it happens all the time. They might have not wanted the money in the bank in fear it could be seized based on wrong assumptions. Once they(the authorities) have the money you have to fight to get it back and even if you prove you did nothing illegal you might not see a dime of it. Whomever has the money has the upper hand. If they had all the money they could have just agreed to give some of it back just to make it all go away.
