Sports betting offers the closest parallel among other gambling products. The cash-out button lets a bettor settle a wager early at a price set by the operator’s model, converting an uncertain future into a certain present for a small margin, much as the purchase button converts an uncertain wait into certain entry. Both bonus buy slots and cash-out markets are priced so that the convenience is roughly neutral in expectation, and both have prompted similar regulatory questions about whether instant options accelerate spending. Players who understand one grasp the other.
