Kevin Adkisson, the chief revenue officer of MicroStrategy, a software intelligence firm that holds bitcoin on its balance sheet, has resigned from his position. Adkisson will continue to work with the company in an advisory capacity during a transition period. The reason for his departure is unclear, and the company has not yet commented on the matter. MicroStrategy's president and CEO, Phong Le, will take over Adkisson's responsibilities as head of the company's sales organization and sales function. The departure comes as MicroStrategy continues to purchase bitcoin, with its total holdings now worth around $4.6 billion.
