Quitting your job to have more time in bitcoin is not really a bad move, IF you are a white collar worker or working in office with stressful environment and give you a little time for yourself. Well it is still risky to do that because if there is some unfortunate thing to happen to bitcoin, finding another job will be difficult, especially now a days. If you still want to have a stable income, I suggest that you can do less stressful and time consuming jobs like online buy and sell, blogging, micro jobs and other home jobs.
