PayPal sells Ethereum directly to customers in supported geographical areas, however currently you cannot withdraw it to an external wallet. Most exchanges don't accept PayPal as a payment method since its buyer protection allows the buyer to reverse the transaction and that opens up the option for fraud (you can read more about this here). However, if you're willing to pay a price there are several ways you can buy Ethereum with PayPal. Coinbase and eToro are two exchanges that accept PayPal for Ethereum, with Coinbase being the easier of the two to withdraw from. Alternatively, you could use a peer-to-peer platform such as Paxful or LocalCryptos, but you’ll want to personally evaluate the seller before making a purchase.
