There are a lot of issues and questions on KYC and country restrictions OP should address all issues, if they want an extra or to get more people to have a recall on your casino better launch a signature campaign, we have a lot of good marketing managers and they are going to guide you how to maximize your promotion here in Bitcointalk.
Unfortunately, op have not posted a single comment here since my last comment and query yesterday, I just checked his profile and saw that he was online today around 8 am (forum time), I personally believe that he's been here and have read all the comment and questions but I am also confused as to why he hasn't tried to address some of them.
Anyways, you have advised well, marketing the casino through a signature ad campaign is also something I and several other forum users have suggested to the op, hopefully, he is already making arrangement for that.
There are several online gambling casinos this days, the competition is very high, and only those who spend good time and money on marketing will stand high at the end of the day, I hope op takes the marketing suggestions serious.
