Cryptocurrency is not difficult to understand. The principles are quite elementary and it is created in such a way that a greater percentage of the people will understand and embrace its concept. It is rather made up of simple numerous concepts as new projects enter the Blockchain.
I think so they learn about it and experience the delivery and acceptance of the coin, they will know the basics and only more learning, they will definitely be familiar with. but for the people first to hear the word cryptocurrency, it would be difficult to understand especially if they were not very techy.
