I think the forum is not the biggest source of players in probably all crypto casinos and sports betting sites. I think Bitcointalk is also probably not the place of marketing where most referrals are coming from. I could be wrong of course but that's my impression.
I know that Bitcointalk is contributing very well to the growth and success of the casinos that are promoted here. But leaving Bitcointalk won't probably cause these casinos to fall and lose their clients.
During the early days, when most people still did not believe in crypto.
This forum was the best for them because it hit the exact people that they need for their ads. Yeah, maybe not right now but still there's the exact reason why every crypto casino is in here it's one of the most effective ways to hit their niche.
There's an attachment already to them and that's why there's no need for them to leave and they can just stop or continue at their own will if they want to as per as advertising and marketing.
For sure there are some long time running campaigns doesnt really mind off about on how much hits they do able to get out from their signature campaign whether its still relevant or worth or not but still they do consider
out to continue for the sake of exposure and awareness of its existence without boggling about hooking up players as much as they could.As long they do able to sustain then that what surely counts
and it do turns out to be a behavior on where most business would actually do the same thing.
Some do see for it to be beneficial and some do see for it to be pointless.It all matters to them but having ads on this forum i must say which is something that needed
specially for those new players or owners in the industry.
