Tesla's Bitcoin has been sold, or will be sold, according to Elon Musk. In response to a tweet about how much hate he's receiving, Musk says, "Indeed." Bitcoin's price plummeted by nearly $5,000 in response to the tweet, falling to $44,700. Musk also went after podcaster Peter McCormack for criticising Bitcoin's environmental effect on the planet. Musk is a co-founder of PayPal and a vocal supporter of Bitcoin.
