ICO and IEO are for raising funds, what about bounty? To create awareness around the web to get more investors right? This makes it two ways for projects to gain investors, I would have said ' why do new projects need bounty hunters for then' but bounty hunters are playing a big role here as you can see that's why we keep seeing bounty campaigns from IEO projects, although not all of IEO cares about bounties
There are only a few crowdfunding projects that succeeded without the help of bounty hunters, 90% of them always do a bounty campaign, it's free marketing for their project and crowdfunding, if the project fails to generate enough funds they are likely to delay or lock bounty hunters rewards, they don't want bounty hunters dumping first their token so they lock it or delay payment.
It's been the process when new projects needs traffics and possible investors, the service of bounty hunters are needed to bring awareness and bring
traffics to the website, Regarding to the delays that's mostly the case where developers are keeping the stake to avoid huge dumped though it isn't the
hunters who really affecting the value but those early investors and the developing team itself.
