If you really think to quit your job I would suggest you not to do that, cause probably you are not ready for that, even in terms of financial independence. You always need to have constant source of money - real job, and then you can try to make money with Bitcoin. If you will have enough from bitcoin to continue your life with a % from earned money, then ok, quit, but not earlier. Another way to became good trader and share you experience with other people and make it your own job. But I will repeat: don't quit from your real job for now.
