The $14 billion marketcap of Bitcoin is a good story for mainstream media. And the Chinese media did release stories as expected. But is the market really driven by Chinese capital market demand or it is just another bubble? You will see the real driving force at the end of this story.
I think BTC value is real not bubble once traditional currency is reducing value itself due to inflation or weak internal economy. so to prevent currency reduction, They must keep Bitcoins now.
That's what a economy man would do in his best judgement.
