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.
I do think so because those who are into bounty programs would be more updated on every changes that will happen in the market due to different experiences on bounty programs. Investors are knowledgeable about cryptos ofcourse but we can't hide the fact that they are only focused most of the time on their invested tokens and not the cryptomarket in general. In my opinion, bounty hunters do understand cryptos more.
