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
ICO and IEO don't work anymore. If you tune in to the market, you get to notice that investors don't like them anymore. And for the promoters, there will always be a place for them. It can be bounty but I also see that it's getting saturated too but in other sorts of marketing and promotion, they still exist and will have a place if ever a project wants to increase their viewership and targets for specific market and niche.
