This is quite risky bro. You decided not to pay for school fees to invest on something you are not a hundred percent sure. Yes, investing is not so bad only if you have an allocated money for it. But risking an amount that is supposed to be spent on a need or something more important is not a thing I would do. Spend your extra money only. You already said it, you are still a student. Your future depends on your decisions. Not all investment decisions are okay, especially if you risked something that should be your primary priority.
