Well, that didn’t take long. Yesterday, China’s longest running bitcoin exchange, BTC China, announced it will suspend its local trading service at the end of this month, and today the country’s two other major exchanges — Huobi and OKCoin — followed suit to say they will cease at the end of October.

The writing was on the wall when The Wall Street Journal reported on Monday that the Chinese government intended to shut down bitcoin exchanges after banning ICOs the previous week. Government officials then began meeting with exchanges this week to bring about the trading suspensions, a source with knowledge of discussions told TechCrunch.
