The price you're looking at is the "global average", i.e. the price considering all currencies. 789.00 is the USD average.
I see. At least that makes more sense.
Why would they put a global average for other currencies converted to USD? For example, that would make the average higher because China's Bitcoin price is higher than USA's.
If I'm buying something in America, I'm not buying it in China or with Yuan.
I suppose the only explanation would be that Bitcoin is a global currency and can't be separated from a single country?
