The first rule of making money on sports is using money management. Never bet 5 units on one bet and 50 units on another bet. In other words never chase a bet. You need a bankroll to start. $100 to $10,000 will all work. I never bet over 5% of my bankroll on a single bet.This allows you to get through the losing days and get to the winning days.You need to win over 52% at -110 juice  to win money. All the pro's use proper money management. If you want to get paid like a pro you need to bet like a pro.
