Over the years there have been a lot of crypto-based-based projects where the business owners offer shares in the form of coins they produce with different kinds of promotions including bounty programs, until when will the gift program remain?
It depends on what you mean, if you mean a particular bounty then the one that decides is the owner of the campaign if he decides that he got enough exposition he can end the bounty and pay those that participated in it, but if you mean for how long the bounties are going to remain in the forum this is something that only the owner of the forum can decide.
