i would happly do that...i like earning more bitcoins than working for the whole day getting some money!!.....and the best part is that we can always earn bitcoins at any time:)
Every job in the internet is not going to be forever,if you are still young and you are in a working age, its not a good idea to quit a job...besides, your knowledge about your field might also decline in each year that you are not practicing your profession.. but if you are earning more than what you earn in your day job and you are not worried about your career anymore then its good to quit a day job..
That's what i scared about bitcoin. I have a good earning on bitcoin, and i scare someday bitcoin will be dead. That's why i think better not quit my job in real life.
