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.
I strongly agree on you bro crypto is a really big rollercoaster and have a huge risk.
He shouldn't invest the money allocated for his schooling because on market dip it will all be loss.
Spend the money you got on more important thing than bitcoin or altcoins because its such a big gamble.
Bitcoin price is volatile and putting money that you need cannot rely on for profit because you are not sure when you gonna gain profit or the profit can earn before you need it for paying school fees. You have to use the money which is not going to spend soon because it takes time before you earn good profit.
