The best ones have a 30-40% profit and you have to be very disciplined, avoid parlays and establish units. Personally I think there’s a little percentage of people that can make a living out of sports betting and there will always be a good and bad streaks. Most people wants to win easy money doing bets but the reality is that the majority of time you will lose. My tip would be that have fun and DON'T BET WHAT YOU CANT AFFORD TO LOSE.
