Bitcoin has gyrated to Musk’s views for months since Tesla announced a $1.5 billion bitcoin purchase in February and said it would take the cryptocurrency in payment. He later said the electric car maker would not accept bitcoin due to concerns over how mining the currency requires high energy use and contributes to climate change.
“When there’s confirmation of reasonable (~50%) clean energy usage by miners with positive future trend, Tesla will resume allowing Bitcoin transactions,” Musk said on Twitter on Sunday.
Bitcoin rallied over 9% after that message, breaking above its 20-day moving average, and climbed further in Asia to hit $39,838.92.
“Musk’s words caused bitcoin to surge,” said Simon Peters, market analyst at eToro. It was last up 0.5% at $39,189, straining to escape the relatively tight trading range of this month.
The market was also supported by software company and major bitcoin-backer MicroStrategy raising half a billion dollars to buy bitcoin, said Bobby Ong, co-founder of crypto analytics website CoinGecko.
Bitcoin is up about a third this year but has collapsed from a record peak above $60,000 amid a regulatory crackdown in China and Musk’s apparently wavering enthusiasm for it. Telsa stock is down about 30% since the company’s bitcoin purchase.
