Facebook Libra has faced many regulatory headwinds since its whitepaper went public. Paypal is now afraid of being in the crosshairs of the federal regulators and so has ditched the project and VISA and Mastercard might do the same. While I believe these are setbacks for Facebook, I still do think they will press on forward and launch either in 2020 or 2021 and it will still be big. I think governments are just stonewalling it right now until the Fed can launch its own stablecoin.
