Irregardless, it's good news for Bitcoin. it means its spreading. Another few million people now know about Bitcoin, and from that people will tell their friends & family.
It's just great to see the news spreading, and as a result people have seen further potential in Bitcoin, and the price has been driven up.
regardless of how many Bitcoin's the Chinese purchase, I don't see how this is anything but great news. People just want the prices to go down so they can re buy in...
