I've been selling on eBay since 2000 - this is a bad idea. Paypal transactions that are digital based (gift card codes, iTunes codes, BTC) have no recourse for a chargeback.
You will almost certainly be the victim of a chargeback
No less than 1/3 buyers have charged back after paying with Paypal. I guess that's why they don't mind paying $220+ per bit coin and paypal always sides with them.
