In my opinion, it is not impossible but it is somehow hard to achieve. It can be a college course but what job you will get right after?  I think you can learn by yourself to do job in crypto, no college degree needed so I think this will not be becoming a major in college. It can be part of the curriculum as a subject in a specified course but not a major subject so that this can help student to be able to have their own source of income even if the are just studying. I think before it is implemented, there will be several discussions about it and I think it will be debated whether cryptocurrency will be taught to college.
