Okay i checked the site, the design is too look professional.
The site gives me a nostalgic feeling of trading and roulette game combination.
Moreover can i ask about the max bet and min bet amount? What's the bankroll of the site?
It would be even great, if you can add more details of the site here like accepted currencies and minimum withdraw etc.
Moreover you can also Design the Announcement thread here with some catchy texts and images to gather more attention.
Wish you happy business Op.
