You have been using this for over ten years now and you have had more profits than losses. It's hard to believe that such a betting system can work for such a long period of time. Placing multiple bets at the same time is very risky because there's a high chance of losing everything. You also claim to be a pro at this strategy. If this is really true then you must become really successful from gambling now. If you can show us some winnings for us to be convinced that you are as good as you are then this would be valid.
