I continue what I started on the other forum here since it’s more appropriate.
I believe you should cut the phone ring when you edit, it will annoy users at best and break their concentration.
In the second video, rather than exploring how money on the accounts evolve when the users stop trading, you could also point out that they actually might be exchanging in a balanced way - same in, same out -, which is more realistic.
One important fact to emphasize is that monetary creation is a form of power to decide what is value and what is not value. In the current system, banks and rich investors have the monopoly to decide what has value. Obviously, they favor anything that will make them richer, and nothing else. So they create money only according to that criterion. With the Libre Currency, this power is distributed to the whole population (at least the ones who decide to use that currency). I know you’ve spoken a few words about it, but I believe it should be stressed even more - and put forward at the beginning rather than at the end.
