A bounty Hunter is not an investor. He becomes an investor if he buys the token/coin. Most hunters will dump their token when they get paid and move over to another project. A bounty Hunter is a promoter, that is shilling a project to his own circle of influence.
Bounty hunters are workers and investors are investors,
the capital that must be spent by bounty hunters is time, and investors are money,
the difference is clear, so who will hold on longer, of course, the bounty hunter will win because they don't have a target,
it's different from investors who have a selling target .
It's not "time" they are spending, it is just wasting time at that point and never seen them to work very well at all. I have been involved in crypto for nearly a decade and I can easily say that bounties are the worst form of marketing ever.
I think it's quite important to remember that if some bot looking accounts shill you, that's not going to get investors invest into you, some people think that if you do bounty and airdrop, that's going to get people to be interested but we all know that it is not going to work and we are not going to see that make a difference. Just realize that it is not going to be a big deal, and we shouldn't really be caring about it all that much. I hope that the best thing to do at this case is to forget about bounties and just find another method to make money.
I disagree with you in some of your points here. It is true that some bounty Hunter make a mess of a project by making post like bots on social media without really actually shilling the project, and this sometimes can be counter productive for the project. But, on the other hand, there are some very good article out there that were written by hunters for a particular project and has helped a lot in letting people know more about a project.
So, don't just generalize, just because some are stupid enough to be making silly post without direction.
