For me, and I am sure for other people as well, it doesn't have much value when Chinese exchanges go through certain price levels in advance of the western exchanges. It will be taken seriously as soon as Bitstamp, Kraken, BTC-E, Bitfinex, etc, reach such levels. China is now around $10 ahead of the western exchanges, which means that if they go up another $10-$15 in the coming days, that we'll see exchanges globally sit at the $800 levels. If it will happen, then it happens somewhere next week, if not, then we'll most likely head down a bit, or remain around current levels till the end of this year.
But how is it possible? Aren't western people also participating on those Chinese exchanges? And if not what is preventing them from joining? Or maybe the $10 difference doesn't give you a possibility to make money on that. But still I can't understand why is there a difference.
