With my experience learning it’s quite obvious that it’s a simple concept to understand if you take time learning about it and not rushing the process. We the community make it look like learning about bitcoin is a very hard thing to do and this discourage new users who would had picked interests in the currency. Sending and receiving bitcoin isn’t difficult but the other areas that are very hard to some extent.
They learned from a theory that there was no basis I think. In this case I myself am not difficult in getting to know cryptocurrency. Since we need to know what we are cryptocurrency for, I myself entered because I wanted to make money, and soon I understood about bitcoin. I think that way is better than having to learn from a lot of theories or books.
