This followed a report from local media (in Chinese) saying that the exchange had received a verbal notice to halt trading from Shanghai’s financial regulator. >BTCC said on Twitter that it was closing its domestic exchange, which operates at BTCChina.com, in response to a Sept. 4 notice from China’s central bank that forbade trading in cryptographic tokens issued through “initial coin offerings.” The exchange had traded a token called ICOCoin, which was started by a BTCC co-founder. The regulatory notice did not explicitly ban trading in digital currencies such as bitcoin and ether—but BTCC will shut down its trading of such currencies for Chinese customers as well.
