Bitcoin for some people worth the risk they took,going full at bitcoin,i would consider it if had no family under me,soo its better to let bitcoin as an extra income .
if you can earning more than realjob why not..? the future of bitcoin is very greatfull, if goverment adopt bitcoin technology each people will interesting to use it and we will see new digital era.
It will be too risky if you are doing that because then your life will depended on a currency and that is quite bad if that happens because you also can see that the value is now not even high.
And than you also even dont know what is going to happen next with your life, it is better to have a daily job and see Bitcoin as a hobby or small bonus.
