i thought china banned bitcoin?
"On 5 December 2013, China Central Bank barred financial institutions from handling Bitcoin transactions, moving to regulate the virtual currency. The People's Bank of China said financial institutions and payment companies can’t give pricing in Bitcoin, buy and sell the virtual currency or insure Bitcoin-linked products, according to a statement on the central bank’s website. On 16 December it was speculated that the People's Bank of China had issued a new ban on third-party payment processors from doing business with Bitcoin exchanges, however a statement from BTC China suggests this isn't accurate, and rather payment processors had voluntarily withdrawn their services. Trading bitcoins by individuals is however legal in China."
