I'm not sure if this is exactly necessary. I don't think that it is. Yes it would be a good thing to happen, but not really necessary. I think that it is something that they can learn at anytime if they are interested in it.  Cryptocurrency is growing daily, and a lot of persons are getting to know about it, so whoever picks interest in it, can choose to go out of their way to stay updated about it, and be a part of it.
