I really don't think it's a scam, I believe it's a first trial step for PayPal and if they see some profit making opportunity they will take it and some more features for users will come later.
It is not scam. It is on testing step for the developers of Paypal. Soon they will announce for ready to use cryptocurrency service as they have promised to start in quarter one 2021. We need to wait patiently and give them time to be prepared for the next step.
