BTCChina announced tonight that they will stop all trading on Sept. 30, 2017 and Dragon TV aired that all domestic exchanges will be shut down.

After carefully considering the “Seven Regulatory Bodies’ Announcement on Preventing Risks Associated With Token Fundraising,” BTCChina has decided to:

1. Immediately stop accepting new account registrations on BTCChina Exchange.

2. Stop all trading on BTCChina Exchange on Saturday, September 30th.

We apologize for the inconvenience. Please note that BTCChina Pool is not affected; customers will still be able to use our mining pool services.
