Due to huge backlash from the regulators it seems FB are killing of libra.
Wow what a GOLDEN opportunity for a 3rd party developer to add-on to FB (think whatsapp as a hanger-on app)
If it could be developed to run inside FB it has had enough publicity (as a concept) it would be huge imho.
Time will tell
