Using Paypal to Sell BTC or Buy = 70% chance of a chargeback.
I got chargedback on ebay (not related to bitcoins) , however with/without ebay, Paypal will always side with the buyers. To paypal, you are basically selling "Air" to someone, and that someone can easily claim chargeback. Only way out of this is by getting the buyer to dispute and then, if the buyer is genuine of course.... get the person to close the dispute in favour of you and then he/she wont be able to chargeback again but don't take my word for it.
I hate paypal.
I understand your concerns but this is almost impossible in case of sending funds to friends and family as gift. There is 10% risk if you accept funds via this "channel".
