I do once again quietly make the point, where else will you get treated any better outside of the US??? From the people I met in the Costa Rican government I can tell you this, if a book there goes under you might as well write off your funds from day one. Any action like this not only would they ask you for a local lawyer, but they would probably require you to pay some fee or tax by showing up in a local bank, then require you to stand in some 2 hour line in a government office. The few that did that would then find out just as the money might come to them, the government passes a law to make sure the gringos don't get a thing. Or if you prefer ask people about what Curacao did for them when Aces went under. Even in Nevada there are plenty of stories of people needing to fight court cases for years to get nothing in the end. This is just a cautionary tale of what risks are taken betting with books anywhere and if it ends up most players get paid something out of Panama, that would actually be one of the best outcomes to ever happen from a book that went bad.
I do think your worries about filing for money are completely misplaced as well. The Wire Act involves people or entities in the business of wagering, not people placing wagers themselves. There is just no way for it to be prosecuted because as I have said numerous times there is not one single law on the federal law books that declares betting or gambling a crime. Only running a business is defined as a crime.
