according to your own screen shot your script is increasing your payout by .01 indefinitely while infinitely mutliplying your bet. your increasing your risk by 7 or by 2 and increasing the payout stop .01 every round. eventually if you had enough money you'd be betting millions due to those multiples and your payout exit point would be pretty high as well. You clearly don't know how to play probability with that math.
your always risking more than you won meaning you only lose by your own math.
up your risk on loss, decrease on win. and keep a consistent payout....
