- While in-game and able to hit that huge win, already planning what they will do with their winning money. But since they have lots of plans, satisfaction doesn't have a limit, and they want to win more. Therefore, just continue to play. In the end, no cashout happened.
I believe it is because a lot of gamblers think they might be on some lucky strike so they will try to maximize their luck as much as possible. They always want to keep going and make their profit bigger than what it is but in the process they will just keep losing until it is no more.
The best thing to do is to cash out at least half and keep playing with the other half for an ensured profit.
