Brother, there's an entire genre of scamming where the scammers spend months building rapport with their victims, usually without ever asking for anything, before "cashing out". One day is nothing.

Wouldn't a wait time like 2 hours with some jitter make it more difficult for a scammer to pursue the case? People aren't going to be willing to stay on the phone for hours at a time. With 24 hour wait, the scammer could just schedule another call for the next day.
