Representatives of the Hong Kong exchange OKEx said that the information spread on the Internet that the site is involved in manipulating prices in the bitcoin futures market is untrue.
We, as a trading platform, do not make profit from the price volatility, but generate income from trading fees. We have not reason to, and have never and will not, manipulate the prices of any of our market.
It is also noted that the images that appeared in social networks and allegedly evidence of manipulation are fake. In addition, the exchange added that the site will have new rules that should prevent the repetition of the situation on March 30:
At 5:00-6:30 on Mar 30, 2018 (Hong Kong Time), the price of BTC quarterly futures contract was manipulated by a group of people, making it fall significantly below the BTC index. To protect the interests of our customers and to eliminate the adverse effects induced, we decided to rollback the futures trading data (according to OKEx Futures Trading User Agreement 6.2). In light of this problem, new "Price limit rules" were immediately launched to prevent similar incidents from occurring. We deeply apologize for the inconvenience caused.
On March 31, a Chinese trader, who opened a major position on bitcoin futures, threatened to commit suicide in front of the OKEx office, claiming that the liquidation of his position was done wrongly.
