I would say that bounty campaigns can indeed grow the crypto community, although there are many who doubt it.
We need to know that with a bounty campaign, it will be easier for people to recognize the crypto projects we are promoting. In this way, of course, ordinary people or new investors will join the project, but of course it is not easy and there is no 100% guarantee that it will succeed.
However, with this bounty campaign, from my experience, the average crypto community from the projects I participate in is mostly growing and getting more and more followers.
