Bitcoin is not totally legalized and well known to people. It depends on the government especially department of education to allow bitcoin subject at school. Hopefully bitcoin teaching in college will happen because it would be a great advantage to the new generation in order to easily adopt the future currency which is bitcoin. That's my thought.
Yes, bitcoin is still banned in many countries, so I think it is still impossible to introduce related courses at university.
Yes, I also think that just like my side, the teacher has to ask friends like friends, and can only say that even if the university introduces relevant courses, there is no teacher who can teach.
