Bitcoin jumps after Elon Musk says Tesla may use the crypto in future

Bitcoin jumped above $39,000 after Elon Musk said Tesla Inc. would resume transactions with the cryptocurrency when mining is done with more clean energy.

The electric-car maker will allow Bitcoin transactions again “when there’s confirmation of reasonable (~50%) clean energy usage by miners with positive future trend,” Musk, Tesla’s chief executive officer, said in a tweet.

His posting was in reply to a report in Cointelegraph, which cited Magda Wierzycka, executive chair of South African asset manager Sygnia, as saying Musk’s recent tweets on Bitcoin should have prompted an investigation by the U.S. Securities and Exchange Commission.
