I think you don't need that subject in schools, may be in University and it will be hard to teach, as there is lack of teachers and there needs to be topics to be developed! And let's say for example a business, how to run a chain store, there is no such a subjects for people to teach, I mean there is subjects like economy, business management and ect. but some people can run and set up a business from 0 and most can't do it, same here! You either get it or either don't, you can't teach someone to make money out of cryptocurrency as out of 100%, only 10 to 20% of investors will make money and the other's will lose! That's a reality
