I ever heard that people choose to quit their job for doing some crypto job. Whether it is trading, mining, or bounty. But I think that's the worst idea. Maybe they think that kind job like that can earn many profit but they doesn't looking at the risk and keep do it. Look at the market, they stay red and it will hard to get profit from investing or trading. GPU price is more expensive as well as a lot of capital to be spent when starting mining. Also Bounty Hunter has bad condition right now with too many SCAM ICO which caused some of them just wasted their time and doesn't earn anything.
How they can earn money for daily need if only depends on the crypto?
I know someone who gave that exact reason for quitting their job. lol. Though I guess, in their case, their family is actually wealthy enough that they won't go hungry even if they don't have a job. Nevertheless, I agree that for someone who doesn't have that luxury, keeping their job would be better, doing crypto on the side. Atleast they could earn extra cash on top of their salary.
