if for my own, bitcoin is my main income, because in the real world I do not or have not worked. because I was told to go to college first by my parents and should not work first.
Digital Currencies do not really need a long amount of time since you can just invest on it and then just live it while you are studying. I know a lot of students that are still studying but they are still doing their investments on Digital Currencies. Time management is needed even as a student, I guess spending some time on digital currencies is also great.
