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.
If someone has a part-time job while a student, then he can definitely participate in Bitcoin investment if he has guardians to bear his expenses and his source of income is prudent. If he does not have a prudent source of income, then it is better for him not to invest. Not everyone's situation is the same. Many have family education and gain practical knowledge by doing part-time jobs along with their studies. But earning money is not their main purpose. Most of the time, such a person's money is prudent for investment. If such a person wants to invest in Bitcoin with that money, then maybe it can be a very good step for him.
But if the purpose of a student's part-time job is to earn money and if he does not have any guardians to bear the expenses, then maybe it is wrong for him to invest in Bitcoin. Maybe sometimes he will have something left after bearing the expenses at the end of the month, but if he thinks that it is unnecessary and invests in Bitcoin, then he may make a mistake. Because a student's expenses increase unexpectedly and his emergencies come frequently. Since he does not have a dependent person to help him in such a situation, I think it is necessary to always have sufficient cash flow reserves for him.
Taking money from his parents and investing in Bitcoin will not always be the right move. If the money taken from your parents is never to be accounted for or if it is given to you for life, then it may be right to invest with that money. But if the money taken from your parents has to be returned someday, then that will also be included in the loan and investing with a loan will not be the right thing to do. Even if your parents have to give a little accountability for that money, it may be better to discuss it with your parents before investing with that money. In this case, your parents should also be prepared to lose that money. Because you have to be careful, so that there is no problem in your family about this issue.
