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 not think so. Investors are people who spend a lot of time in order to study a project, a team, a whitepaper and so on. They will never give money to the project unless they are 100% sure that the project is not a scam.
And bounty hunters often do not even read Whitepaper. They are still on the project, they are paid money for the promotion of the project
