So with bitcoin is important to focus on the present and not on the future as much.
paypal never did any kind of cooperation with bitcoin because they are mainly against it, unless you know something that I haven't heard about yet!
besides paypal and all those other online payment systems are going to become obsolete in a couple of years and cryptocurrencies will replace all of them because they so much cheaper and better to use for online payments.
Maybe paypal is against bitcoin because they have a hunch what potential resides in bitcoin and the blockchain?
