A number of China’s top bitcoin exchanges are preparing to suspend their services following instructions from the government. BTC China, one of the country’s top three, became the first to officially make the move after it announced today that will stop all trading for China-based customers from September 30.

The company said other services, including its BTCC Pool for miners, are not impacted and will continue to run. There’s no word on when, or indeed whether, it will reintroduce trading.
