How did you know that there's very less amount of people investing in ICO's? Did you experience it with your own project or you're just guessing? Don't you know that mostly bounty hunters are also investing to the ICO project where they are involved when they think that the project has a great potential. And when it comes to bounty campaign, it's surely profitable for every ICO's that are using this to advertise their project, because this is the best advertising services that is most effective and most used here in this forum.
