I think you are downplaying the severity of this context, I don't think it will go down well with casinos if you are always winning. Now, let's be clear about this, you are a regular gambler who loses, and at a point, you started gaining for a period of time, after which you slipped back to your losing streaks, my bother, you are not a threat. But you can't compare yourself with a gambler who hardly loses but wins every time and withdraws his winning. It takes a great grace for that gambler to remain with that casino because it's kind of strange and such could be perceived as a threat to the casino. This is especially possible if he is increasing his wagers to win even bigger.
