Besides I use a diffrent method which I dont recommend you yet because it is quite confusing. I start with a bet and if it looses I double or triple the amount if it looses again I triple the lost total amount like first bet + second bet and go like this. At the end of the day I m always winning no matter what I never go minus. But to be able to do that you need nerves like steel! Be patient and follow the rules strictly! It is an advanced method called as martingale system.
Plus dont forget to make a fortune just by placing one bet and doubling your money. It is unrealistic. You need a system and follow it for months. I always end up with + after 8/9 months of betting on a league or season. These are the basics you need to follow. It is never fortune destiny or chance. You just need to be patient, control yourself (dont be greedy) and learn to accept when you loose a day dont be aggressive and wait for the next days.
