I may say it is a job for the reasons that they are money involved and it has a energy exert. Bounty hunters are job because we use this to earn money and gaining more profits. I worked on this for my extra income.
Bounty hunters cannot be the main work. For that simple reason that from this occupation it is not possible to get constant stable profit that would provide to the person all his requirements.
I also agree, it is not all bounty campaign may we participated has a good payout, some of it are also scam so it is better that a bounty hunter job as a part time job only, so whatever happens here of our crypto earnings it is still better to have fix monthly income.
