This must be part of the reason facebook/zuckerberg is looking into cryptos & blockchain....fear of loss. They have the audience but it may just be a way to increase profitability for the organization, not for their users.
We'll see what they roll out...
FB may introduce their own currency at some point. It makes sense when their userbase is bigger than any country and if they want people to trade there more effectively. How they back it up is another issue
It will be interesting to see what they roll out.
