The average person will have a hard time processing cryptocurrency, unless they possess a basic understanding of investing and the stock marketing. It's not an easy craft to pick up on, but it's a priceless skill to have if you can. I'm not really good with creating analogies on the spot, but in order to explain crypto ro a person, so that there is a general understanding of its utility, you have to break it down to them, doing so in a manner or level they can relate to and understand.
