Do you think bounty hunters are a job in your spare time, additional income or is it the main job and the main income of people?
You can use bounty hunting as a secondary source of income but not as your main job. There is no assurance to the bounty campaigns, that is why do not leave your personal job for it.
I agree also, bounty campaign on this time are only few that are good so it is better to make your bounty job as a part time job only, but for some of us here bounty hunting is their full time job.
