There are 2 courses on saylor.org. Check them both out, one is for devs which I'm going through now and one is more for non devs and has a lot more high level stuff like comparisons of money etc and not so much cryptography detail for eg. Both a good. 

 Thank you very much, I'm starting this course more in depth. I had been looking for something like this for some time. 

 It's really quite good course man. It's based a lot of Anton Antonopolous and Stephan Livera amongst others. These would be good people to follow also on YT or wherever. Not sure if they are here!
