Don't quit your job to invest in bitcoin, it is a very unwise option to take, investing in bitcoin is not a business, neither is it time consuming, so you can keep your other sources of income or your jobs in real life and still comfortably invest in bitcoin.
It depends, I mean if you're not happy about your job, where you lose a lot of confidence, pride, self-love, because of the toxic workplace, then it's okay to leave, do not hesitate. Maybe that's what OP meant, or he is not happy about the salary he is getting every month which doesn't worth the energy and time he put per month.
Having full time in cryptocurrency is a bossy move, you can sleep anytime, you can wake up anytime, and you can do whatever you want. It's toxic free that could help anyone to earn more if done in a right way.
