Icos look for bounty hunters to promote their project through the power of social media.Sometimes, some of these hunters also double as ico investors. But it looks like bounty hunters understand ICOs project and are able to determine very good projects before they invest because of their experiences in different projects.
Yes I can say that bounty hunters can be investors. Because bounty hunters are always updated about the project. And a bounty hunter can see if the project is really worth it.
So there's a reason why bounty hunter will invest in ICO.
