But I don't think anything like this will happen with hunnyplay because they already said they are thinking about their signature campaign and also I see that hunnyplay.io has the one active thread in the gambling board of this forum.
This goes beyond signature campaigns, the hunnyplay team needs to remain dynamic and innovative to stay in front of the market. This can only be possible with a creative team who will constantly seek ways to keep things attractive.
Because the community has creative individuals, suggestions and tips from here can always aid he team make creative decisions.
You are right though, it's just like I did mentioned in one of my comment some long time ago, that's like several weeks back, having alot of customers using a product is not always about marketing, whether it be a signature ad campaign, or normal Google ads within apps and sites, it's more about having a good product that attracts users by itself, whereby any user who comes around to test the product will hardly want to leave, but rather, he or she will go on to invite their friends and family who also make use of such product, and those friends and or family members he invited will also go on to invite their own friends and family as well.
In the end, this proves the saying that the best marketing is the free one, the one you did not spend your money to do, but the one where customers are the ones doing the marketing for you even without you paying them directly or indirectly.
And today, it takes a great amount of didication from a very creative team to build such a product, and listening to community of who have experience in such products is also important, as some of the community members may have some really nice idea, which can be what a product needs to become the next multi billion dollar product/project.
