What do you not understand about cryptocurrency?

Hi all Naturally, all of us regulars here are cryptographic/cryptocurrency experts with enough knowledge to make sound trading and investment decisions. Without this important knowledge we wouldn’t be making such large purchases of Bitcoin. Recently I have noticed some people to be far more knowledgeable than others, particularly on this forum, and some people saying there are things they’d like to know more about.

A question to all: if there is anything you do not fundamentally or partially understand about cryptocurrency, what would it be? Please explain why you don’t know it.

Obviously some people know everything they need to at this current time, in which case please reply with, “Nothing required for me” Looking forward to hearing people‘s responses and what they are needing schooling on.
