Did you saw this quotes from the "sellers guide"?QuoteNOTICE: Please do not create listings that instruct customers to pay outside of escrow, or are used for any purpose other than to list an item to be sold for the listed price using the site checkout system. QuoteEscrow HedgingDISCLAIMER: at this point, escrow hedging is experimental and we reserve the right to discontinue it without notice.Unfortunately, the bitcoin exchange rate isn't as stable as we would all like it to be, and can fluctuate wildly in a matter of hours, let alone the days or weeks it takes for a package to arrive. Because of this, there is a real danger that the bitcoins being held in your escrow account will lose value by the time your customers finalize their orders. So, we've given you the option to hedge the future payments you are expecting from escrow such that the dollar value of the payment doesn't change as the bitcoin exchange rate changes.For example, someone purchases one of your 10 btc listings. The dollar value of the order when purchased is $100. Now, a week later when the transaction is finalized, those 10 btc are no longer worth $100, they're worth $50! Because you hedged the escrow, you won't get paid 10 btc, you'll get 20 btc equaling the original value of $100. Of course, the opposite is also true. If bitcoins appreciate in value while your payment is in escrow, you'll get fewer bitcoins, but they will still equal the original dollar value.The option to turn off or on escrow hedging can be found on your "settings" page. While it is on, the payments for any orders placed with you will be hedged. Payments for orders placed while it is off will not be hedged, but any hedged orders still not finalized will remain hedged.On your account page, your escrow balances are split up between hedged and unhedged orders. All orders are unhedged until you confirm shipment, at which point, if you are set to hedge, the payment for the order will show up on the dollar side of your escrow balance.
