Open up a "Prop shop" where I set up a bunch of machines that operate like a game but for trading forex. You can go to my place and get on one of he machines, slide your money in the cash slot (5/10/20 etc.. bills) And you can trade forex. if you bust, you can insert more cash or slide your credit card for credit. All it would take is some software guys to build a fun trading platform and guys to put it together in a slot machine style case. But it is not gambling, its technically investing and you can advertise that losses are tax deductible unlike casinos which only deduct from winnings. Would this be legal??
