Tesla’s Musk Renews Critique of Bitcoin, Talks Up Dogecoin

Tesla’s Musk Renews Critique of Bitcoin, Talks Up Dogecoin

Elon Musk stepped up his criticism of Bitcoin as environmentally unsustainable while also signaling support for another digital coin and saying he remains a believer in cryptocurrency. The Tesla Inc. chief executive officer said in a tweet Thursday he worries about “massive use” of coal and other carbon-intensive energy to generate electricity needed to mine digital currency. That followed an earlier Twitter post of a chart from the University of Cambridge showing Bitcoin’s electricity consumption has skyrocketed this year.

It marked the second day he’s criticized crypto mining and follows a decision to suspend Tesla car purchases using Bitcoin, a move that roiled digital currency markets over the past 24 hours. But Musk also signaled his support for another digital currency Thursday in a separate tweet that said he is working with Dogecoin developers to “improve system transaction efficiency.”

Musk has been an early corporate champion of adopting digital currencies and has helped spur the popularity of Dogecoin, a cryptocurrency started as a joke in 2013. In February, Tesla said it had purchased $1.5 billion in Bitcoin and planned to accept it as a payment, triggering a rally in its own stock as well as the currency. But the about-face on Wednesday sent the value of it and other cryptocurrencies sliding.
