As far as I can observe being a teacher, I am definitely happy that my students are involve in cryptocurrencies and they earn for themselves and help their families. But, their school perfomance is getting worse. Please give your thoughts how will you help students to earn and at the same time it won't affect their school works?
I've ever answered similiar this question, but different in a case. Blockchain system, crypto, and everything is a good subject to study everyone. Not matter still as student, higher student, or professional. In your case, you find a problem with student. Some country have a rule or regulation about bank account and finance. I hope in your country have it. It restrict anyone to make a bank account if they are under 18 yo. It makes your student can't to withdraw their coin into their currency, even they can buy anything in internet by bitcoin, but the choices were limited. So, you can tell them to keep their bitcoin or altcoin till they get a bank account. It called an investment. Good luck for your job, sir. Honestly, I've a dream to be a teacher....
