PayPal is strict and just joined the bandwagon. With the first days of their adoption, they don't have a withdraw option and this option was just allowed later on. If you've got some funds in there, withdraw the fiat and deposit it on the exchanges like Binance or any other popular exchanges that's easier to access.
It did not "just join the bandwagon", it was here for a few years now. But still, I wouldn't put even $1 of crypto on a PayPal account if I were you. Because that's the method a lot of fraudsters are using to cash out, so they are going to freeze the account and ask you for additional documents.
If you use PayPal for other stuff (and you probably do), it's not worth it IMO.
