The average casino gambler needs to get more into sportsbook betting. It's difficult when you dont know much about sports, but its such an underrated gem. Its common to see people recover a majority of their balance with a few well placed multis.
Betting on multis will in the long term always be negative and you will only loose money. It is much better to bet on single games with good odds. I tracked for 2 years my performance for all bets I placed and found out that betting on multis (even only a 2-fold) is not interesting.
