The University of Nicosia is well known for their MOOC "Introduction to Digital Currency." When I started a deep dive into Bitcoin, I enrolled in the Spring 2022 class. The course content ranges from the magical to the mundane. The sections on Bitcoin for the Spring class were taught by @aantonop (sessions 2-7). All of them are freely available on Youtube so it is worth enrolling in the free course for the lessons? Yes. The course presentations and background material are good to great, and the feedback from the quizzes reinforces your understanding and retention. The sections on money and central banking, taught by Antonis Polemitis were also very good and gave a good background on the subject. Missing was any exploration of Austrian Economics. The sections on DeFi were the low point of the course.
