What ever you do, never buy cryptocurrency on Paypal !
tldr; buying cryptocurrency on Paypal means:
1. You can't use it for anything.
2. Paypal can lock you out of your account at any time.
I also learned from reading the FAQ that Paypal controls the private keys associated with any cryptocurrency you buy through Paypal. What that means is you have only illusory control of your cryptocurrency, not actual control.
