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 most bounty hunters migrated from ico investment just like myself. Going back to fully participate in ICOs because of the high volatility of the market. I rather buy coins at x10 ico price from the exchange and wait for moon
