Coinbase’s president and chief operating officer, Asiff Hirji, has left the company, Coinbase announced today in an email to staff. He will be replaced by Emilie Choi, who was previously Coinbase’s vice president of corporate and business development. Tina Bhatnagar, Coinbase’s vice president of operations and technology, also is expected to leave her role in the next few months, Coinbase said in the same email, according to people familiar with the matter.

The executive shakeup comes just a few weeks after the departure of Balaji Srinivasan, Coinbase’s chief technology officer. In the last year, a number of Coinbase’s top executives have departed, including several who oversaw the company’s institutional business. Coinbase is one of the most widely used cryptocurrency exchanges and was valued at $8 billion in a funding round in October.
