Are you sure PayPal supports BTC and other crypto? Because I can't find a crypto option or wallet on my PayPal account, it only supports local currency.
Or is PayPal BTC not supported in my country yet?
If you are not base on US, then you won't see this option for now.
I've created a similar thread,
PayPal launches "Pay with Crypto".
If the option is only for residents in the US then that doesn't make any sense. I am actually not a fan of PayPal maybe because it doesn't work in my location. If you value anonymity I don't think you should be paying for anything on PayPal using your Crypto-currency.
While setting up PayPal you are already giving out so details. But I will be looking at this thread if there is actually a decentralised way to buy things online using Bitcoin.
