There are a few benefits to consider when it comes to a rollover or wagering requirement. First, it can help to keep players from cashing out immediately after receiving a bonus. This gives the casino time to earn back some of the money they would otherwise lose on bonuses. Second, it can act as a deterrent to bonus abuse, as players will need to wager a certain amount before they can withdraw any winnings. Finally, it provides an incentive for players to keep playing, as they can only cash out once they have met the requirements.
