paypal already became an old fashoin method to pay
Old is Gold, you haven't heard that? Paypal is a very old method of payment. but still paypal is primary payment source of millions of peoples and thousands of online companies and marketplaces.
But when the question of bitcoin come to front then people also do not care for gold and they want bitcoin because the benefits of bitcoin are more higher than any other payment processor and many people are using paypal because on these places bitcoin is not currently available.
