I will give my opinion on your question here.
1. You need to be a Bounty Manager.
Is that a prerequisite? A new account won't be able to do it?
I can just do it, but you have to be a purchased cooper member to be able to take pictures, but if the beginner account doesn't show pictures then it's less interesting.
But it's better to leave it to a famous manager to increase the audience more even though there is no guarantee.
2. I don't see any bounties now.
Has the bounties and hunters phase faded away?
Bounties still exist, some are still active you can search the board.
I don't think it's fading, it's just that now many projects are not promising bounty hunters, so most of the value is not valuable at all.
