I think bitcoin will overcome the paypal. Because first, bitcoin is becoming more pupular. It is ver easy to use with the different kinds of transactions. Next is that bitcoin has a very good potential in the market. But it should be use all over the world before bitcoin overcome paypal.
I can't understand why we expect bitcoin to surpass paypal method? We don't need this at all.
Paypal is full central organization and it's working perfectly. Bitcoin has many problems.
