Tesla CEO Elon Musk said the company will resume bitcoin transactions once it confirms there is reasonable clean energy usage by miners.
“When there’s confirmation of reasonable (~50%) clean energy usage by miners with positive future trend, Tesla will resume allowing Bitcoin transactions,” Musk wrote in a tweet.
Musk, who has been a major promoter of cryptocurrencies, announced in May that Tesla would no longer accept bitcoin for car purchases.
The billionaire said that he believed cryptocurrency has a promising future, but it cannot be at great cost to the environment.
Bitcoin, the world’s biggest and best-known cryptocurrency, was up 40.7% on Sunday from the year’s low of $27,734 on Jan. 4.
