I usually don't have a average bet per game. I usually go where my instinct are, if I should bet small or big. Because I think if I have an average bet I will not win at all its just like going with the flow. So If I feel like I should bet small then I bet small then if I fell that I should bet big then I go with it. Also with this kind of betting of mine, I felt satisfied somewhat because I enjoy and I follow myself with my betting instinct.
That's also good as long as we are betting based on a controllable amount of money. Betting with average is good if you are doing gambling regularly and it could be one of the best effective bankroll management you will be making, in sports betting I use a method of flat betting rather than martingale. Winning will come at the right time and we do not need to force it, when our skills and luck will connive on a certain moment, for sure it will result to a bigger profit.
