Interesting! I love the idea of showing video to orange pill.
I wonder how long is the class? We've less than 1 hour here. The videos you took for lesson plans are about 1 hour.
Our classes are 75 minutes twice a week. So perfect length for these two videos but we only had time for the first because of how much interest there was in bitcoin (plus I can ramble on about bitcoin for a long time)

Ok. I've never had a class for so long in my school or college. So, the second video is assignment, right?

No I didn't assign it to them to watch, it's just optional now
