I'm wondering why they have selected you as their marketing manager! You have created the ANN thread here and made only one response in that. Now you have asked for the suggestions and disappeared again. You aren't acting like a responsible manager here. And this is not the way to do the marketing. Firstly suggest your admin to add Bitcoin and other top altcoins in the casino. Then try to stay active in this forum and give update in your ANN thread on daily basis. Your website will start getting few new users. And your website will gain significant user by spending some money for advertising. As example: signature campaign, twitter giveaway.
