OP possibly might have that in mind to sound a caution to the community but his major priority is his fund's recovery first which made him want to put up a recovery bounty I am skeptical of the bounty as well because sometimes all these can come up as a scam in disguise.
Fair enough. I understand that but putting a bounty recovery is going to make people more doubtful and scare them off. In my estimation, he should count his losses, learn his lessons and move on. Reputable and properly licensed casinos are easy to find on the internet. If one can't find it, then ask a question. A reply, I can assure him , he'll always get.
I believe OP learnt his lesson the hard way in gambling with unknown casino and for the fact that OP has found his way here, he now must have seen lots of reputable and big casinos that are reliable and trustworthy to play with here.
From the response he got from the casino, I think if OP is innocent and is not satisfied with the result he just would want to make things straight with them but sometimes things of this nature happens to teach lessons which I believe OP did learnt from and I also believe OP would next time do a good research before having getting involved with a casino but however there are big casinos with good reputation here so no cause for alarm if OP decides to identify with one.
