Earning is quite low now, don't even think to quit your job for bounty hunting if you have a decent salary.
Some bounty hunters are too exaggerated with their belief that they can earn more than their day jobs through bounty hunting. Just because they managed to earn quite good somehow during the ATH days, they'd think that quitting job is essential and replace it with this unstable source.
If you have a lot of free time during your day job and loyal boss you could try to do twitter/fb bounty and signature campaigns. If you are a creative video or article maker with a lot of subscribers, earnings can be quite good though.
Though you can have a lot of ways to earn through bounties, what if that bounty became scam?
