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?
Bounties isn't gift at all, it is a partly a job that need effort to promote their ICO. So it is depends the developer, if they think is useless to do bounty then they will not using bounty program. But so far as i know, bounties is effective way to promote ICO project.
