Now I am trying something like the same but differently. I pick a big football club and I bet that it will lose. If I lose my bet, I double it and so on.
Just look for a better odds the team and bet some 60% of your main funds or so.
When you bet on 50%-50% then the odds are equal. You can increase your chances in dice by choosing a wider range of number where your bet is profitable. It is up to you what the odds you are playing will be. If you try to have a small profit then you can increase the bet. But if you chance bigger profits then the odds are bigger. The strategy doesn't change however...
