If people don't have an interest in a thing, don't expect them to see the good side of that thing. Bitcoin is interesting because you study it and has understood how it work, the people that has refused to learn about it are the people who don't care about it or have interest in it.
Yes, even though Bitcoin is relatively simple to understand and people are not interested in it, they will always perceive it as something difficult to understand. That is everything about bitcoins, and not just bitcoins. Whatever a person undertakes in life, if he or she does not have a full hole for themself, they will not be able to achieve their goals. That is the most important thing for anyone interested in Bitcoin to know: they must grasp how it works.
There is no way a person with some money invested on Bitcoin is going to say he is having difficulty in understanding Bitcoin, before you invest in anything you must first understand what's about and how it work, so it's not a mystery that people don't understand Bitcoin.
