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.
The OP of this discussion shouldn't be taken seriously. He has created so many threads that lacks quality and has always failed to give clarification or explanation to his ideas. He is a well known spammer in the politics and society and Economics boards.
Gambling is unpredictable. Thus, there is no single betting strategy that will lead to regular wins. He may have made some profit from using this strategy, but there is no certainty that any individual could have the same results. This is the more reason why we should always do our research before applying what we read on the internet.
