This rather clearly IS being driven by China. Go to Coinmarketcap, click on Bitcoin, and then select the markets tab:
http://coinmarketcap.com/currencies/bitcoin/#marketsNow take a look at the major non-Chinese exchanges (say the Top 10 of the list). Chinese exchanges are 0-fee, so they are excluded from the top of the list - you'll find them at the bottom. At the moment the Chinese exchanges are running
$50 above the non-China exchanges. Redditors are saying that was $70 a few hours ago. So there is apparently crazy demand for bitcoin on the Chinese exchanges, and that is pulling up the price everywhere else.
If you know how to slip across the border with (lots of) Chinese fiat or bitcoins, you could make a killing right now.
this is interesting but this is not a new thing.
there was actually a topic about this in the bitcoin discussion section claiming that all the bitcoin daily volume is from China and wanted to conclude bitcoin is being controlled by Chinese, blah blah...
Chinese have always been in bitcoin and pumping it, and also this is nothing new that the price on their exchangers are higher and this is mostly because of converting their money to USD when comparing the price.
