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.
That is very risky decision. Your money saved at bank fir paying your school fee is not suggested to invest in bitcoin. Probably, you may consider it right because you can get profit as expected but it is not usually happened like that.So you should invest only your extra money or idle funds.
