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?
Yes, but for me, bounty is free time work. So bounty is just a job when you have free time.
If anyone considers bounty as a job and for a fixed income it is a big mistake. Because the bounty cannot be predicted when it will pay. And it's better to work in the real world or start trading to get fixed results. And the bounty is used as additional work.
