After the eventful demise of Libra, Facebook and its mark Zuckerberg actually never given up the idea of having his own huge and successful cryptocurrency network which is more of a stablecoin. Now, we have Diem and it would be a good idea to fist have it tested on the social media platforms it has under control like Facebook, Instagram and WhatsApp. they can start using Diem for paying advertising fees and other services within the network and allow people in this ecosystem to also be using the said coin for each other. There is a big potential of Diem all because there is already a waiting market for it. This is a matter of execution and not being the focus of so much regulatory power and interference.
