Great post @juanmolina. Those were long 3 parts :)
Discussions regarding Libra and Facebook are very intense lately and I personally don't know yet what to think about it.
I'm mostly interested how FED and other central banks will react if they will realize that Libra is a threat for current financial system.
Personally I will not put my trust in Facebook and I don't think I will ever use Libra. However I will surely pay attention to this project as it may turn our financial world up-side-down....
