I've never heard of this site before. I think the importance of signature campaigns can be understood from here. You have a very nice 4-letter domain, but you haven't done much about promotion.
You can define weekly free bets and spins to attract more users to the site. You can give this right to high-level ranks in the forum to prevent multi accounts. In the Games & Rounds section, you can open various prediction competition threads. Such campaigns usually attract the user to the site.
