There is no need for signed messages and things, I just think you are good guy and that's it. Time will tell did I have good feeling about you or not. Good luck, and see you for a week.
Edit: I gave loans to people that I met on some dice sites and casinos, but here never until now. I was reading new post`s and saw you topic and I just go with a feeling. You lost a lot, 9 btc is big money. I gamble a lot ( for much less ) but feeling when we lose is same. Good luck once again and see you.
Repaid sorry for late payment (discussed over PM's)
