Yeah, I saw your email. I believe there is no universal Bitcoin price and each marketplace has its own and the 'average' price you mentioned really does depend on which marketplaces your include in your statistics, right? If that site included us, maybe the average price would be different

Either way, for fiat currencies, there is a Forex exchange rate that you see online on various sites and then there is the exchange rate of your local bank which is most likely going to be different, but you can't say that's misleading, can you?
