BitMEX has overhauled its executive team, with CEO Stephan Lutz, CFO Ina Steiner and Chief Growth Officer Raphael Polansky all leaving the crypto derivatives exchange. Former global general counsel and chief operating officer Peter Wilkinson has taken over as CEO. Lutz resigned from the CEO role, while the departures of Steiner and Polansky remove three senior leaders at once from an exchange already under pressure to reposition itself.
