Chinese regulators have banned financial institutions from using Bitcoin, warning that the virtual currency could be used for illegal activities and speculation. Chinas central bank, the Peoples Bank of China, announced the decision in a statement released Thursday, though it stopped short of banning Bitcoin altogether. Individuals are still free to use the digital currency in China, albeit at their own risk. Bitcoin has seen its popularity soar in China, with its value recently surpassing $1,000 on BitStamp, an online exchange.
