True. The problem is they don't know they don't know.

That's the problem with the common Bitcoiner matras. They are often true, but the Bitcoiners repeating them did not arrive at them as a conclusion, they are repeating them because their Bitcoiner friends are repeating them.

They think they understand, but they don't.

The problem is that the answers to these questions are quite hard and don't fit in the "Bitcoin fixes this" matra format.
