It must be noted that, unlike typical crypto exchanges and wallets, you won’t be able to move your cryptocurrency out of PayPal. Thus, PayPal only gives you access to the public address of your cryptocurrency and not any private key.
Although this is quite ‘anti-crypto’ and runs against the core ideas of cryptocurrencies, it does imply that PayPal crypto customers will be able to trace their cost base more easily, which will make tax filing easier.
