If bitcoin or crypto-currency is fully accepted or legal in our country, that would be the proper time to introduce it in college. Aside from additional learnings to the students, it can also help them support financially for their schooling and future needs.
I believe you are beginning to see crypto trading groups in colleges already, the young people understand crypto and see its potential. The only challenge for the young students is a lack of money to invest, but as they get old they will earn more for crypto.
