Actually it is cheaper to send via Paypal now than to send via bitcoin, at least domestically.
But overall I think bitcoin is still killing it, because it has gained so much adoption over the past few years.
Bitcoin is definitely exceeding paypal by a large margin on the gambling scene though because it is anonymous and easy to deposit and withdraw without having to worry about account limitation by paypal.
bitcoin leads over PayPal due to its convenient transaction ,no much details needed ,the only advantage now of PayPal it is widely used for shopping purposes unlike in bitcoin that is not known yet for shopping needs.
