Paypal will never embrace BTC, because BTC is a natural enemy for Paypal. It endangers their position.
If you have btc, why do you need paypal? Is btc not designed to be able to trade without that 3rd party? It seems completely un-intuitive to have paypal in the mix.
Thing is, the bitcoin community has a huge education burden that needs to be picked up. Also the scammers and the junk need to be relegated to a lower level of noise. Also, the 'wallet' concept needs to be more secure and simpler to administer and it is getting there! Also, we need exchanges that are hardened and trustworthy. So, ease of use, reliability, security and education ... what's not to like and who needs paypal?
