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, this is why i recommend all people who are new to crypto get involved in bounty programs. it's a good way to learn about the business and the market in general before having to risk real money
