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. Even after this incident I keep on losing every week what I earn from campaign.
