Sure, paypal is the big kid on the block right now, but who's to say they won't start accepting bitcoin as one of many international currencies?
(Edit: I just added "after 5 years" and "never" as additional poll choices.)
I do not use paypal because I knew it does not like cryptocurrency. I am a pro coins.ph user and I like to say that it is a good wallet than any other. I currently using it in transacting with my gas, load and bills. It is okay for me that paypal never accept cryptocurrency because there are wallets that I can use so that, I can cash out my BTC.
