Elon Musk says his social media posts about meme cryptocurrency dogecoin are "just meant to be jokes" and his true allegiance lies elsewhere.

The Tesla and SpaceX boss admitted in an interview on the Clubhouse app on Sunday night he is an advocate of bitcoin, just days after changing his Twitter bio to promote that cryptocurrency in a move that boosted its value by up to 20 percent.
