I think nobody really need PayPal,  but an alternative payment method might be good.

It is common to see some discounts using PayPal payment method in Brazil. It might be safe to use it when you are buying something in website where you don't feel safe using your credit card.

It would not be a problem for me if I could add some bitcoin to my PayPal account and pay for an Airline company using PayPal, for example. Sadly, payal and cryptocurrencies are available  only US AFAIK.
