To answer my own question in title:
I am receiving current sign payments directly to casino, and I have spent some. Because why not?

What about you?
I was in a signature campaign SWC poker, and they sent payment on their platform. Usually I loved to play poker games. So whenver I did received my payment I used to play games. If I won some extra chips there I always do gamble more. For me it was fun , like come-on I'm still on profit zone. As long as I've these extra winnings no fears to lose some. Which basically leads me to play poker on their platform regular.
One more thing if you do use their platform regular you will used to know about them. So from next time you can suggest someone boldly that platform. Which I found casino site owner's fabour. So year Ig they do this for their own sake
