I will say bounty hunter can be act as a part time jobs but do not consider it as a full time jobs, which only participate it when you have free time. Bounty hunter is just like investing both of your time and money in an unknown project. However, it normally take some time to get profits, therefore a complete and fully understanding of the project is very critical. Even the project is cancelled or suspended, you still lose much if you don not invest all the time and money in it.
