Welcome to educational Bitcoin videos. The purpose of this course is to provide an introduction to Bitcoin. It is divided into three bigger parts, each consisting of three or four short videos. You can watch these videos easily when you have a bit of free time and rewatch them for better understanding.
Part one is about the theory of Bitcoin. What it is or isn't, what you can do with it or can't do with it, and what you should or shouldn't do with it.
