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 don't think so. People don't usually spend their bitcoins on something physical items. You remember what happened to the pizza guy right? He paid in BTC 10,000 for a few boxxes of pizza. That's what I think people taught about now. Digital money can never replace real money.
