During The B Word virtual conference held on Wednesday, Elon Musk wore a shirt printed with the Bitcoin logo, with the words "THE EVOLUTION OF MONEY" written on it, talked about his views on Bitcoin. 

He revealed that Tesla, SpaceX, and himself all own Bitcoin. Because SpaceX is privately owned, it was previously unknown that this company holds cryptocurrencies.

Musk also said he also owns Ethereum and Dogecoin, but his Bitcoin position is much more than the other two.
