Hunters are considered an investors if they will hold and will not dump their earned tokens. Bounties were get paid because of their hardwork as hardwork is not free so by earning the tokens they should also consider holding the tokens to be good as investors too.
I think it will be different even though the bounty hunters are both holding their assets. investors give their money to buy the desired assets. But Bounty Hunter promotes tokens to be bought by investors. actually Bounty Hunter is part of the team that participated in the success of the project. cannot be considered as an investor.
