If there partnership with Paxos is official I think that Paypal has a good chance that they will be offering crypto trading because there is really no other reason why Paypal will partner up with a crypto related firm without them being at least interested in a crypto related business. I know that Paypal before is against any kind of crypto industry related business as they are also against crypto related transactions being used in their service but with them partnering up with crypto related business I think this is a good sign to say that Paypal have changed their minds with crypto.
If they are seriously looking for them as a backer then it would make complete sense to go with them.
Solely because they are regulated in the toughest regulation area in the planet being New York where they don't allow exchanges to even operate there until they payout for the license to do so which is in the millions.
And paxos has been approved to provide anything to do with blockchain and operating with bitcoin in the state of New york by obtaining this license.
So they are smart in doing it this way if they are looking to really get into accepting a type of crypto with their platform to their already 277 million customers.
