I use my funds that came from signature campaigns, preferably, I'm waiting for my balance to reach my minimum preferred balance before starting to play on amy casino. There were just few times in which I'll make some deposits from which aren't awarder from bitcointalk.
Myself too does the same, but this went out of my control. As a result I've lost big depositing and gambling. This way I was in big debt and now I'm feeling bad for what I've done. I've shared my story on a separate post Be a Responsible Gambler. Controlling ourselves is the hardest thing in gambling. Even if we set our budget/limit before start gambling, we may jump into a situation when we cant control ourselves. It is a human nature if you ask me, greed is something that hard to control but if gambling turns you into a big debt then you did it really wrong.

Even after this incident I keep on losing every week what I earn from campaign. 
Why dont you learn from your own experience? I think you need to find someone to help you as it seems you are addicted already as you cant even stop after you were in a big debt because of gambling.
