It was silly to leave the main job and going in for Bounty hunting as it can only be a hobby, especially today. As of now, I would recommend you to self-develop in different areas with the help of online courses to find the area where you can earn money working for yourself instead of boss.
Bounties are just another easy way for making money and are quick in and out game. For constant and consistent inflow of money pure investment has to be made in businesses.
It could be either in cryptocurrency or in traditional market. Whichever way is easy to you because what maters the most is how much you make in the market. Investment in the cryptocurrency market might also take you time to make profits out of it due to slow market but bear in mind that the market is slow and not impotent.
