I am looking to see how many people sell on eBay. If you do sell on eBay and would like to be able to use Bitcoin, please let us know here and why. Just doing some general research.
But isn't any seller already able to accept BTC for their eBay listings? I've seen quite a few sellers that accepted bitcoins.
Although it must be a bit of pain, you would have to instruct the buyer to check the rate himself and then calculate and send the right BTC amount, or you would have to keep the buyer waiting for instructions in private message.
OP, do you have any automated service in mind? If so, that sounds interesting.
