TS,the method you introduced is actually The Martingale.People have been using this method to gamble for ages and yet they still lose.Want to know why? visit wizardofodds.com and you will know the TRUTH about betting systems.Fact is,no betting system in this world can overcome the house edge,that means the casino will ALWAYS win.unless you do card counting in blackjack which gives you a very very slim player advantage,and this takes patience and a lot of hours in the casino for you to make any meaningful profit.

you should do more research before you started this thread.
