While it is true that you invest with the bank with binary options, it is not true that the bank makes money when you lose money. Your broker makes money, when all its customers combined make less money than they invest.
The assumption that the bank is trying to make money from every single one of its customers is ridiculous. The bank is trying to make money in total. To achieve that goal, the bank has to make sure that some of its customers are becoming rich men by using their service.
In truth, binary options shift money from unsuccessful to successful traders. All you have to do is make sure that you come out on the right side of this deal. With binary options, your profits are the losses of other traders, just as with any financial investment.
