For my own little Understanding, bitcoin is a digital assets, which is something you can see, but not touching it, where is classified as a virtual money. Therefore bitcoin is a movement currency that fluctuating at any given time, which require knowledge or learning to understand how it works.
You don't actually be in depth technical knowledge having bitcoin. By just simply having a bitcoin wallet, you can start using it and understand its fluctuations through owning it. I've taught my friends that way but with the very minimal amount like $2 worth of bitcoin.
In that case, they can see how fluctuation works because they don't have an idea how fluctuations work too. They are totally zero knowledge about the volatility of it and looking at how it works made them realize that it's too volatile and can move emotions, positively and negatively.
