Bethog already has began and maintained good marketing in this forum by a signature campaign that has been running for many months. From which, I believe they have good budget for marketing and it is only matter of time until they see need of expanding to other marketing types.
If I remember correctly, I think we had some other marketing campaigns, maybe not campaigns but contests held in the Games and Rounds section, managed by LM himself, and I think those contests and giveaways can also be good initiatives for platforms to attract more users towards their platforms. I'll explain how it can be good opportunities.
Most platforms that run these giveaways and contests usually give out the rewards within the platform, by asking the participants to create an account where the reward will be deposited, and believe it or not, when a gambler gets their reward in a gambling platform, the urge to gamble will surely hit them when they see the balance, and they might think of trying out the platform the games it has.
That way, if they start gambling, they might end up losing the funds, and if they like the platform, they might become a regular customer after that.
