Yes of course investors are more valuable even it's simply thinking if investors people not investing in a project then those project never gain access. For explaining about bounty hunter, there just keep promote a project by earn free coins. Afterwards if bounty hunter not hold there coin then investors will take loss fund.
Its not free money, they are getting money for completing the tasks which is given to them so blaming the hunters for liquidating the token is not the right thing and this is due to more bounty allocations by the project team and it simply shows that team is not giving value to the investors and the project itself.
