I think the several experiences in working with different projects has made bounty hunters very experienced. They can determine a good project from the start but some of the investors are just new and do not really determine a promising project from a scam and in the end scammers run away with their money. So bounty hunters who invest in ICOs will never invest if they do not trust the project.
Headhunters are first and foremost people who constantly monitor the situation with projects. Perhaps some investors may less understand the project. But this is not always the case, because before investing in a project, you need to carefully study it, get to know the project team. Not least the idea of the project itself.
