I don't think the Bounty program is over.
Of course, the ICO market has died a lot, but I think the Bounty program will continue until a new marketing plan is released.
Or if there is a new marketing plan that I don't know about, please let me know.
As long as there is a project that needs a marketing,an investors,supporters and audience then the bounty program will not be dead or over. A project without audience,supporters and investors is already a dead one therefore they need it as it is part of their marketing technique in order to reach their goals.
Though there are plenty of marketing techniques aside from this one but with regards to crypto industry bounty campaigns is the most suitable marketing technique for their project to become successful.
