Show HN: Udemy course explaining Bitcoin fundamentals

Coupon code for the course(100% free): HODLER

I've been working on a course focused on explaining the fundamentals of Bitcoin. It touches on some more technical concepts but in a easy and simple way. Most courses I've found are geared towards investing, which is what most people are interested in anyway, but I consistently see tons of confusion over basic Bitcoin concepts. A lot of courses seem to have good content, but not many seem to have good visuals showing exactly how everything works, which is what i've tried to improve on. Let me know what you guys think and what could be improved, thanks!
