I think that someday it will definitely happen and schools will talk about cryptocurrency. But before that happens, cryptocurrencies must become a truly mass phenomenon. The market is still too young and tools for simple interaction with cryptocurrency are not ready for users far from technologies.
People are only interested in Blockchain technology and very few people in the school are interested in the coins in this market. I think the application of Blockchain technology is absolutely necessary as it can help our lives and if you are a passionate programmer of this technology then surely you will have a good future.
Well, teaching cryptocurrencies school, if ever it will happen, should automatically includes the learning about blockchain too because they come together all the time in my opinion and they don't have to be interested in it. They just have to learn it in preparation for the future innovation of cryptos.
