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.
Bonus system is the next state because when the site gets high amount of traffic and organic users they can give bonus facility to keep the users for long time. But when a new site enters the gambling marketing, its first task is to market its site very well. and attract users. Signature campaigns help a lot in marketing a site in this regard. And that's why reputable casinos spend thousands of dollars to run long-time signature campaign here. So if new sites run long time signature campaign here with a big budget they might get a positive result.
Yes, the first thing that must be done is to do a promotion so that the site they are building can be known by many people. And spending a big budget is also proportional to what they will get later, they don't look at how much they will have spent now, but they have to see how many users will be part of them. In getting money, you have to be lured with money, that's what I hear a lot now. Talking about bonuses that will be offered later can be done in tandem with their promotions. But for me the bonus is not the main thing, because there is something more important than that, we have to know what users want so that they are interested in visiting the site.
