Investing in student life!

Good luck to all friends. I have a close younger brother. He is a student. But he is interested in investing. After learning about Bitcoin from someone, he invested in Bitcoin with his tiffin money. And later he made some profit from his investment. This increased his interest in investing. Later, he got a part-time job along with his studies. And he kept investing from his monthly income. And he is still investing. In my opinion, a person spends the most free time during his student life. If he invests in such a state, he will be able to invest stress-free. And he may not need an emergency fund.

My question to the ignorant is, will this harm his studies? Or will he stop his studies and become more interested in investing? Is it right for him to invest during his student life?
