Bounty manage still have good demand but team always looking for perfect guy who can handle their project. If you can gain merit and talent, It'll easier your. you can join under experienced manager as assistant so that you could learn work.
Not all bounty managers need an assistant, especially if he is very experienced in handling the latest bounties and usually the managers also have their own friends who can be invited to be their assistants.
Needs a assistant or not for a bounty manager, i think it’s not depend on the bounty managers experienced. Because who BM managing a couple of bounty projects at the same time when it’s very difficult to maintain as like they have to update spreadsheet weekly also have to assist a lot of hunters. So, here a manager can't handling easily one more bounties when they need to hire assistant.
