bitcoin can win, bitcoin anonymous and easy use, bitcoin can get rerturn because bitcoin price fluctuative
paypal is very dificult use, must verified, and can't get return
What return facility are you talking about. Are you talking about the profit you can get because of the price fluctuation .
There is no race between bitcoin and paypal for that matter. Bitcoin is a currency and paypal is a payment option and the only common factor is that both are virtual payment methods .
