Yuan-denominated Bitcoin has crashed as much as 25% 35% in Chinese trading, plunging from 25,000 yuan to as a low of 16,000 on local exchanges BTCChina (and as low as 20,000 on OKCoin), following confirmation of last week's Caixin report that Beijing would stop cryptocurrency exchange trading. China's second largest exchange, BTC China, said that it would halt all trading on the platform beginning September 30, launching a liquidation panic.
In a statement released on Weibo, BTC China said that it would immediately stops accepting new account registrations on BTCChina Exchange. The decision was made after “carefully considering” Chinese regulatory bodies’ Sept. 4 announcement on preventing risks associated with token fundraising. A google-translated version of the statement:

The immediate result was a sharp plunge in the CNY-denominated price of bitcoin on exchanges like BTC China and OKCoin:
While China no longer dominates cryptocurrency trading - it accounted for nearly 90% of all trading in late 2016 before Beijing launched a series of measures to limit participaton - and is now responsible for less than 40% of global volumes, the Chinese selloff has spooked global markets, pushing bitcoin sharply lower on international exchanges as well like Coinbase, where it was trading at approximately $3,600 last.
A breakdown of global bitcoin exchanges by volume is shown below:
Also notable: as of this moment, China-denominated bitcoin is trading at about 17,000 yuan or just under US$2,500, indicating there is a nearly 30% arb between Chinese and offshore trading.
This isn’t the first time the bitcoin market in China has come under regulatory scrutiny. In early February, major exchanges suspended withdrawals of bitcoin and stepped up their scrutiny of clients after meeting with the central bank.
Emil Chan, vice-president of the Hong Kong Blockchain Society, said it would be difficult for regulators to outlaw bitcoin trading altogether. “There is no option to restrict cross-border sales of bitcoin. It is a smarter move to maintain the operation of the local exchanges if the central bank’s goal is to minimise the outflow of yuan.”
Still, the virtual currency is up more than six times from a year ago, with some participants convinced the bitcoin market is in a bubble. “In fact, the market was too hot. The action taken is an effective action to cool down the global cryptocurrency market,” said Chan.
Meanwhile, Leonhard Weese, president of the Bitcoin Association of Hong Kong, said if China continues to toughen up on regulations to restrict growth in bitcoin, it may drive the business to the city.
“People in China will be more careful about marketing these events, and a lot of that marketing activity will come to Hong Kong in the form of conferences and communities,” said Weese.
It remains to be seen if Chinese bitcoin fans will simply switch to other OTC/bilateral forms of trading, or simply take their trading to neighboring Japan and South Korea which remain eager advocates of trading in the crypto space.
