Tesla Inc.’s Chief Executive Officer Elon Musk said the electric-vehicle manufacturer is suspending purchases with Bitcoin, triggering a slide in the digital currency.

In a post on Twitter Wednesday, Musk cited concerns about “rapidly increasing use of fossil fuels for Bitcoin mining and transactions.” His post said that Tesla might accept other cryptocurrencies “that use <1% of Bitcoin’s energy/transaction.”

Bitcoin dropped as much as 15%, sliding below $50,000 in Asian trading.

Musk’s move comes after Tesla disclosed in February that it had purchased $1.5 billion in Bitcoin and planned to accept it as a payment. That announcement added legitimacy to the cryptocurrency as an increasingly acceptable form of payment and an investment, especially coming from a large member of the S&P 500 with a high-profile CEO who commands a large following among retail investors and the general public.

Tesla’s website, which had a support page dedicated to Bitcoin, noted that Bitcoin was the only cryptocurrency that Tesla accepts in the continental U.S. Musk has also tweeted frequently about Dogecoin, a cryptocurrency started as a joke in 2013 -- and he quipped about being the “Dogefather” before and during his stint hosting the “Saturday Night Live” show on May 8. He tweeted on Tuesday, “Do you want Tesla to accept Doge?”

Tesla’s addition of Bitcoin to its balance sheet was the most visible catalyst during this year’s rally in the digital currency. Bitcoin jumped 16% that day, the biggest one-day gain since the Covid-19 inspired financial markets volatility in March 2020.

Optimism grew after Mastercard Inc., Bank of New York Mellon Corp. and other firms moved to make it easier for customers to use cryptocurrencies, fueling the mainstream resurgence that took Bitcoin from about $29,000 at the end of last year to as high as almost $65,000 in April.

Bitcoin mining is consuming 66 times more electricity than it did back in late 2015, and the carbon emissions associated with it will likely face increasing scrutiny, according to a recent Citigroup Inc. report.

Musk is no stranger to considering the issue of crypto’s environmental impact. Cathie Wood’s Ark Investment Management LLC published a report last month saying that Bitcoin might actually be good for the environment. Twitter Inc.’s Jack Dorsey retweeted a post on the white paper with the comment that Bitcoin “incentivizes renewable energy.” Musk replied to Dorsey’s tweet, saying simply, “True.”

Musk’s tweet on Wednesday took many in the cryptocurrency community by surprise, including Nic Carter, a partner at Castle Investment Management, and a leading voice among defenders of Bitcoin’s energy use.

“Surely he would have done his diligence prior to accepting Bitcoin?’ Carter said. “Very odd and confusing to see this quick reversal.”

It’s unclear what prompted the decision and Musk and Zachary Kirkhorn, Tesla’s chief financial officer, did not respond to an email inquiry for comment. The company’s website still had information about how to make payments via Bitcoin after Musk’s tweet.
