I really hate to bring this up, but I don't really have a choice.
When it was originally stated that bitcoins would be used, it was not specified that payment would be taken through BitPay. While I don't have anything against them as a service, their rates are not reflective of the current exchange rate.
As of the last time I checked, BitPay asks payment in BTC at a rate of 66.783 Euro/1BTC, versus the current price of 73 Euro/1BTC. 73/66.783 = 1.093. I feel that it is unfair to ask bitcoin customers to pay a 9.3% premium for paying in bitcoin, especially when it was not stated beforehand. Had I known this to be the case, I would have used PayPal.
2090Euro / 66.783 (bitpay) = 31.295389545
2090Euro / 73 (mtgox) = 28.630136986
Difference is 2.665252559 BTC × 73 = 194.563436807 Euro
I'm not trying to be difficult, but this would put me in a difficult position. Maybe others have a helpful insight to provide. I know that this was not intentionally done, and that BitPay offers burnin a convenient conversion to fiat. I hope that there is someway to resolve this where everyone is happy. Am I completely off-base here?
