We can only suggest him finishing his study and start Bitcoin. But if his parents give him the money for monthly, he can start into Bitcoin investment. I heard some students can get a part time job that can give him some money. If he have that two things, having money for monthly from his parents and his salary from his part time job, it will be better for him because he can start Bitcoin investment.
That will take many years before it happen and try to see what he provably missed if he didn't do something at early as this.
So I guess what's better option he could take is to use only the extra funds he get after he take all of those things need to pay. Since somehow accumulating Bitcoin coming from extra funds he got is still the best thing he could do. He could just think about that this is his savings then provably everything will work good after he graduates and find high paying job which provably could make everything good on his side especially on his Bitcoin investment.
Uum..that is what he needs to do if he doesn't have money to start. People can't expect from faucets like a few years ago. That's not worth to do but they can start investing in Bitcoin when they have money.
If he has extra funds, that will help him to start but if not, it will be difficult. But if he wants to use other people money, that will not be a good idea because he needs to give back the money. Unless that money is from his parents, he is free doing that and that depend on his negotiation with his parents. So he needs to think what he will do to start his Bitcoin investment.
There's absolutely nothing wrong with deciding to invest from the leftovers you have from your students upkeep. What really matters is planning with what you have. Some people have the opportunity and privilege to come from a better family where parents either hand you a credit card or place you on monthly stipends for sustenance. It won't be out of place to save a percentage for any other purpose as well as bitcoin accumulation. Going into bitcoin accumulation does not mean that you must always maintain your accumulation at a set interval . As someone under parental care, you have very little or no emergency funds, hence your parents do that all.
Back in my high school days, I have seen mates acquire lands from their monthly or weekly stipends even without the knowledge of the parent, some only inform their parents after acquisition of the property. A student who is wise enough to start up bitcoin accumulation from his upkeep when he has excesses could be a better investor when he finally gets his own job after school.
