This video was very good back then. But even for people that do understand basic finance, when describing how bitusd is created by shorting bitusd with the example of Alice and Sam, the vocal description vs. the slides is a bit confusing at some point and I found that it confused me and I wasn't able to clearly explain it to other people.
I think a new version when shorting rules are finalized with priority to interest offered with examples not only with people (Alice, Sam and Bob) but with numerical examples based on orders seen on the BTSX client will be a "must"!
