So, does that mean sellers need to make sure that the btc and the dollar price is somewhat close? I, too had a discrepancy. the difference between the btc price and the dollar price was way off, by 15-20 percent(not in my favor). It would make sense if they took a 24 hour average. Looks like Ill have to check the difference a couple times a day. Just so long as its close, I know it wont be perfect.
