Actually it’s  totally different concept due to its novelty, but once someone get involve into the space of crypto I don't think its that hard to learn it or understand it. And also you need to consider that rypto is a new form of technology and it must be need a lot of time to understand it. I think the best method for understanding crypto is through the social media. To start to make them understand,  just tell them the basic concept of crytocurrency that will not confuse them like it was a digital money. And tell them on how to earn from it, how a transaction can happen etc.
