i like using both...bitcoin is better
I agree bitcoin is better than paypal. And I have some feeling that paypal is going to adopt bitcoin. SO that clearly says that bitcoin is better than paypal. Because if paypal is better than bitcoin, then the developers of bitcoin are the ones who are going to ask paypal to adopt their service. But it tends that paypal is begging for bitcoins adoption.
I can't see PayPal incorporate Bitcoin into their system as it goes against their way of doing business, and what they stands for. Also, the Core developers will not contact companies asking whether or not they are willing to incorporate Bitcoin. They have much more important things to focus on.
You are right since paypal would see bitcoin as an competition with this industry and they would not intend to adopt bitcoin but if paypal would do some innovations and reducing their fee maybe they could somehow maintain their users or clients to use their service, the only one thing i could complain about paypal is their fees thats why i dont hesitate to switch in to bitcoin.
