Good post. I am always looking for new classes on crypto or blockchain. IBM does a free blockchain course through its developerworks program. You get a certificate upon completion. I also found some good courses on Udemy. Currently, I am taking DFIN by Andreas Antonolpoulous (sp?) from the University of Nicosia. He is very respected and so far I have learned a ton from the class. This course is free and also comes with a certificate. They also have a masters and you can pay with BTC.
