Hello,
Facebook cryptocurrency project stool the idea of X8currency
Facebook Libra is same as X8currency.com project
X8currency came first and project team builds value preservation token
Facebook has dual tokens just like X8currency
Libra is backed by fiat currencies and gold just like x8currency
Possibility: X8 project is Libra project
Or Mark Zuckerberg is a plagiarist like he did with facebook
