Tesla's CEO Elon Musk and its CFO Zach Kirkhorn have changed their titles to "Technoking of Tesla" and "Master of Coin," respectively.
The change was announced in Tesla's latest 8-K filing submitted to the U.S. Securities and Exchange Commission on Monday. Musk and Kirkhorn will maintain their respective positions as CEO and CFO.
It is not clear whether the Master of Coin title is about bitcoin, but it appears to be a character in the popular series "Game of Thrones," where the Master of Coin is in charge of the royal treasury and advises the monarch on financial matters.
Kirkhorn, being the CFO, would have been advising Tesla on investments and financial matters. Earlier this year, Tesla invested $1.5 billion of its spare cash into bitcoin as part of the company's corporate treasury management.
The company's bitcoin bet appears to have paid off well so far since the cryptocurrency has surged from around $35,000 levels in January to about $56,000 at the time of writing.
