But, there were cases where enrolment in campaigns done by "invitation". When managers are considering other "establishments" for enrolling, why not "hodling"; which is the whole point of this topic.
Most casino signature campaigns focus more on members with knowledge about gambling. How do you expect a campaign manager to reserve slots for holders who don't have any gambling experience or knowledge? Holding for a long time doesn't also mean that the user has enough knowledge about Bitcoin or the forum. Campaign managers have other criteria for selecting participants and not just merits. And I think they should be allowed to do their job based on the service they are promoting and their discretion. I don't also think it will be difficult for holders with Bitcoin knowledge to be selected by managers in campaigns.
