> I am presuming that if the customer actually made money, these guys would pay them from their own pocket. Set up a company, sell “shares” in Apple or whatever, and don’t actually buy the shares for your costumers. If Apple falls you make bank, and if Apple rises you declare bankruptcy. Either way the costumers loose. That is the difference to market makers who actually buy the asserts, so the customers at worst just have a bunch of less valuable stocks not empty hands.
