If someone is insane enough to sell to you for Paypal then they will charge you a massively large premium to make up for the inevitable scam attempts.
Literally anything other than Paypal will be a better option. Send it to your bank and buy normally. If you don't have a bank find someone who does and pay them to use it. It'll still work out cheaper.
Bitcoin and Paypal don't go well, you are at risk if you think you can use Paypal on Bitcoin,take the safest route take this advice or if you don't want that option trade with someone you already know for a long time or a relative, better be safe than sorry, don't make it a habit to use Paypal to buy Bitcoin
