I won't quit my job, at a moment If I can work on both then it would be useless to quit my job, as doing both is giving me opportunity to earn extra income, So I would prefer to continue with both.
I too, when I am done studying and already working, I would prefer to do both, work while after work I will find bitcoin as an extra, I can't really go fulltime here because my course is not computer related and my studies would be useless if I won't work on a day job....
