Yes paypal use crypto but instead of eth many users was expecting the TRON blockchain its faster cheaper and more used.
Eth transactions still too expensive i hope they start use TRON soon
The Paypal uses the crypto currency over a period of time,you can direct convert of your fiat to USD or now the conversion will be acceptable one in crypto currency.So one can easy covert of your PayPal dollars to any other crypto currency and you no need to worry about the exchange to buy the cryptocurrency.So Paypal accept the tron for the faster transaction,some people still use of ETH in the Paypal.But the better option to use the crypto in the PayPal is Tron using USDT in your wallet balance.
