We're going to keep hearing "Chiba bans Bitcoin" until they actually do.
I do not want to be a dick, but this is a really good read about all this China FUD
http://fintekneeks.com/zerohedge-fakes-bitcoin-panic/. Especially the part, where they point to the fact, that China had a +buy volume during the selling, and how insignificant bitcoin is in a 100 trillion market.
Just a thought.
