Well, upon second thought this could actually be a good buy. Its 330 EURO or $346 for .3 BTC If BTC increase to USD $1,154 than this auction would be under face value. Assuming that the BTC is delivered of course but you are protected by Ebay correct?
I believe you would only be protected for the card/physical item that is shipped to you. I don't think ebay supports sellers for cryptocurrency funds so unless they changed their terms ebay does not protect against unfunded "funded" items and only protects against physical goods descriptions.
