I think that bounty hunting could be considered as a job. For those who do not have any "real job" is it possible to earn some good money investing their time and effort.

There are plenty of activities related to ICO's (translations, moderation, promotion and so on...) that you can do and most of them takes takes a lot of time and efforts.

For me bounty hunting is only one of my hobby and gives me the opportunity to gain some tokens. I just enjoy participating in bounty campaign like signature campaign and twitter campaign.
