The hardest part is the change in perception. When I mention decentralization, they think it's unbelievable and even nonsense.More friends are interested in Bitcoin not because of its technology, but because they hear that they can make money.
Literarily, like bees to flowers and honey badgers to honey that's how humans get attracted to making money too. I think most people first got attracted to Bitcoin for the monetary aspect of it (I don't think it's wrong though) and then became fascinated by its technology. Teaching Bitcoin to a novice without whetting their appetite with the investment part of it where they can make money will be like winking in the dark. Even among my educated friends I still perceive that reluctance in them going the Bitcoin route after several attempts at teaching them. What most of them do is ask how it's fairing, especially whenever Bitcoin soars in price.
