The hardest part is still the regulation in US, which make Libra of Facebook can not issue their own cryptocurrency, so I will wait and see how Paypal will handle it. If it succeeds then chances are it will be key to the market's bull run next year.
The regulation part of facebook's Libra almost killed all the momentum it had gathered. PayPal is an American company too so unless they move to a more crypto-friendly land, I think the same thing will happen to Paypal (If they decide to create their digital assets).
