Just an observation, but I’ve noticed that many casinos with signature campaigns eventually stop, and the community seems to forget about them. Meanwhile, the casinos with long-term campaigns are still popular today. Of course, we can’t deny the popularity of these casinos...Stake, Sportsbet, Rollbit, Duelbits, and Betcoin.ag. Maybe it’s because they run their campaigns long-term, so their presence is seen daily on the forum. So, do you think casinos get significant benefits from having a signature campaign, especially when it’s long-term?
Popularity in which place? If you are merely refering to this forum only, yes those casinos may lose their popularity but it does not guarantee that they will also lose their popularity in general (globally).
In general it depends on the casinos, how do they advertise/promote the product and bear in mind that this forum is not the only place to advertise their product/service.
Even if they stop their campaign here in this forum, they can be popular because of other advertisement so it depends where do you look at.
Popularity is not also depending on campaigns/advertisement because it can be useless if the casino itself is not providing something attractive to the users.
