Ideally it should not effect your life if you are smart user.. I think that bitcoin don't affect your life if you know how to manage your time, very often people wasting their time very bad and than complaining about negative effects of bitcoin.
Collecting bitcoin could affect your life in any way you look at it, Specially if you are not investing your money into bitcoin and just relying on earning it... Day by day you will always think of ways on how you will collect bigger amount.. I think going full time on bitcoin would really affect you, time management would be very difficult compared to working on day job that you only have to work atleast 8 hours a day or sometimes fewer, that way, you still have 16 hours time for your self that you could use in any way you want it..
Time management is crucial especially on the situation. It really depends on an individual if he chooses to go full time or part time of earning bitcoin. It would really affects you if you lend all your time in front of a pc and forgetting your social life and even your time in your family it would be very difficult to choose but if you have proper time management i think you can handle both.
