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.
I think yes. Because usually bounty hunters try to choose only the best projects and why not to invest in them? For me, this is a great opportunity to get free coins in addition to those that I already bought. And it seems to me that people who understand, try to do the same.
