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.

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.
