Stay away from project Libra as much as possible, it doesn't seem that needs to be said often as the reaction from governments and now investors (PayPal, VISA...) is very unfavorable to Facebook.
If the likes of PayPal and MasterCard starts questioning the transparency of Facebook and are concerned about scruntinies from regulators then it's time to pull out.
How will this impact Facebook's Libra as it seems to remain unmoved remains to be seen with time.
