This story is not still clear to me, because I don't think if it is possible for someone to quit his or her business or job and then depend full on bitcoin a doubt. See less be realistic here, because anyone who quit his or her business or his or her job will definitely sell his or her bitcoin investment at early stage of accumulation and in lost when emergencies arises and there are no emergency fund or back up fund for handle those emergencies. See even if someone had been successful through bitcoin is not possible for person to scrab his or her business or job and  then depend fully on bitcoin, why because bitcoin is a long term investment if you want make reasonable profits from it, so you still need that your sources of income to be topping up your bitcoin on a weekly basis or monthly basis. You also need that your source of income be building your building your emergency fund and backup fund for those two funds are very essential when it comes to bitcoin investment.
