These are mostly the same features Bitcoin/Ethereum provides to senders. But the cryptocurrency transactions are nonrepudiable, which is beneficial in some contexts (a friend of mine had his laptop stolen via a PayPal chargeback, and porn sites have had lots of problems opening and keeping credit card merchant accounts) and a drawback in others (the ripped clothing shipment mentioned in a sibling comment).

And of course the main feature of cryptocurrencies is that PayPal can't freeze your account when you try to withdraw money.

Sure, as does Apple & Google pay. I'm not saying PayPal is the only way, but I am frequently faced with either paypal or credit card, and in that situation I will do paypal every single time
