Hi, I was wondering if I should quit my job and focus more on bitcoins? Because I think it might get me even richer without a job? 
No you must not quit on your current job just to focus on bitcoin. Better think of it that it will be more beneficial if you have two sources of income so that you can have greater money on your hand. Focusing on just one will just enable you to earn enough but working on both will give you more than enough. Also you do not have to surrender one because you can easily manage both at the same time.
