if you want to progress and not just rely on being a bounty hunter then it all depends on your skills in this field.

Then, three years ago, it was possible to earn so much money on this that it would be possible from that day not to work to this day and to provide for yourself well. Now many of my friends use this method as an alternative way to earn money, since you wont earn such a lot of money already, and moreover, you cant count on stable income since projects sometimes dont pay for several months.
