The point I am trying to make here is that you are one of our early players and you're aware of how system used to work because that is exactly the same way it still works today. Astonishingly, you didn't have this problem when your investments made some profit nor you had this problem when you won a 18 BTC in a single roll yourself.
Is it ok that I point out a 9btc bet at 50% means a win of 9btc not 18.
