Dive Brief:

• CEO Elon Musk and CFO Zach Kirkhorn have added the titles "Technoking of Tesla" and "Master of Coin," respectively, to their existing titles, electric car company Tesla said in an 8-K filing Monday.

• Kirkhorn’s "Master of Coin" title may reference Tesla’s $1.5 billion investment in Bitcoin it disclosed last month, Bloomberg said.

• "[Musk] and [Kirkhorn] will also maintain their respective positions as chief executive officer and chief financial officer," the regulatory filing said.

Dive Insight:

In a February 10-K filing, the company said it expects to begin accepting bitcoin as a form of payment "in the near future, subject to applicable laws and initially on a limited basis, which we may or may not liquidate upon receipt."

"Master of Coin" is a reference to HBO's popular series Game of Thrones. 

Few other CFOs expect to follow Tesla's lead on the use of, and investment in, cryptocurrency. In a Gartner survey last month, only 5% said they plan to hold Bitcoin or other digital currency as a corporate asset this year. Almost 85% said they don't plan to ever hold the currency. Price volatility is the main reason. 

As of Monday, Bitcoin, the oldest and most widely traded digital coin, was worth about $56,000. 

Coinbase, a cryptocurrency trading platform, earlier this month announced plans to go public, signaling a potential maturing of the industry.
