In sports betting each bettor should have a Minimum Win Size. My Minimum Win Size is 1% of my bankroll. For example if I have a bankroll of $1000 dollars. I will not make a bet that isn’t going to win me at least $10 dollars. Your Minimum Win Size can be anything. My average Minimum Win Size is about 3% of my bankroll, depending on the edge. I will bet anything from 1% – 15% of my bankroll on a sporting event. The point is to establish Minimum Win Size. It may be a percentage of your bankroll or a specific dollar amount. Whatever you decide, be sure to track every bet.
