Do you think that sometime in the future, Bitcoin might overcome Paypal, as it scales in capacity and userbase over the years?
We already have the ability to create our own marketplace with OpenBazaar, that uses Bitcoin as its payment method, so it should be no surprise that the combination of these two may be a fierce competition for both eBay and Paypal.
Nevertheless, feel free to vote on the poll above and express your opinion about it, if desired.

I think no,because in the first place paypal is an online payment manager which allows you to pay any item online.They are holding different kinds of currency which allows you to use it all over the world with legality which the bitcoin cannot give us from now.Bitcoin is a cryptocurrency that allows you to pay with anonymity but it is the actual currency that should be converted to your local currency and it is not legal in all countries so I think no.
