Facebook is finalising plans to launch its own crypto-currency next year.
It is planning to set up a digital payments system in about a dozen countries by the first quarter of 2020
https://www.bbc.com/news/business-48383460Sounds old, but this might be true this time.
Facebook has offices virtually in most parts of the world where they are operating and we know that Facebook platform is a platform used globally, so if Facebook is creating a coin, it will surely be used by its users in different part of the world, but that doesnt mean it will be a global currency as people claim it will be.
Whatever coin Facebook is going to create will be a stable coin to be used by its business members because I dont see how useful it will be to an ordinary user since the coin will be a stable coin purposely or their system and not a general utility coin like BTC or ETH.
