I would continue with my job for sure, I like bitcoin, but I don't have total faith in it looking at the price fluctuation involved, So I will always treat bitcoin as good extra income and nothing else.
Thats the good idea. At anytime leaving day job is not fair. Bitcoin price increases gradually but having much dependence will result in failure, because if you involve completely no time has to be spend on other activities only then you can earn your targeted amount.
