Cash Out is a feature that gives you the opportunity to close out your active bet before the outcome is decided. This allows you to secure part of your winnings or cut your losses as the odds change in or against your favor.

Cashing out can be tempting because it lets you lock in a profit or mitigate your losses. Unfortunately cashing out your bet also has a negative ROI over the long run. Sportsbooks understand their customers can get trigger happy, so they make sure those early cash outs are much lower than they should be.

It's not a simple yes or no answer on whether you should bet on the favorite in a given matchup. It's a matter of value. If you think a favorite is being undervalued by the oddsmaker, then you should consider betting on that team.

The fundamental reason why all martingale-type betting systems fail is that no amount of information about the results of past bets can be used to predict the results of a future bet with accuracy better than chance.
