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 think you should talk to their parents to ask them to talk to their children to remind their children to do not forget their studies. Don't be busy only in bitcoin, they need also to study because they need that to their future and to become prosperous their life of her/his family. Me, as a student I did not forget my studies. I think it depends on their children how to manage their time.
Are these students minor? Or college students? Well it's good that they're exposed already to finances and how to make money but therr's a time for everything especially if it's affecting studies. It's quite alarming if these students are highschoolers
