No, do not quit your job for bounty hunting...It is an on and off business if I may put it that way except you want to fully indulge in coins
and also he can do both , work for 8 hours and just do bounty in free time? quitting a Job means you have a sure source of income but indeed that Bounty hunting is not a assured profit provider .
and also don't complete do bounty instead invest also , excess money from job can do the investing.
Leaving job for full time bounty hunting is fullish work. Im not well known about bounty hunting but in Bitcointalk there is a bounty section. If you hunt bounty form here and leave job for this it's fully fullish work. Because in 2018-2019 every bounty bring success for hunters but now day's bounty can't bring success. So In this time leaving job for bounty not ok..
and also he can do airdrops for some time to make another source of income .
