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.
Actually, you should not even take whatever OP says seriously by the way. He is very active in the political section of the forum in which he shares a lot of questionable content and opens multiple threads with alledged solutions to the biggest problems of humanity. If you asked me, he is just talking from his imagination and he has not actually made such a significant profit from betting in sports as he claims.
Also, keep in mind, the last thing someone with a pretty much very accurate method to win money would do is sharing it with random people on the internet.
It is a matter of common sense, don't you think? You never kill the golden-egg chicken.
