A week after the CFTC filed a lawsuit against BitMEX and its founders, the crypto derivatives exchange announced a change of leadership.

Two defendants in the lawsuit, Arthur Hayes and Samuel Reed, have left their CEO and CTO positions in the exchange operator 100x Group.

Vivien Khoo, who served as a chief operating officer, will become interim CEO.

According to the statement, Hayes, Reed, and fellow exchange co-founder Ben Deal will not hold any positions with the company. In addition, the head of business development Greg Dwyer is taking a leave of absence. He, like the three co-founders of BitMEX, was accused by the US Department of Justice of violating the US Bank Secrecy Act.

Recall that after BitMEX problems with regulators, the analytical company Chainalysis ranked the exchange as a high-risk platform.
