Bitcoin jumped above $39,000 on Sunday on the back of a new tweet from Elon Musk.
The CEO of Tesla called the conditions for resuming the acceptance of BTC by his company.
Tesla will start accepting bitcoin again when its mining is at least half carried out on renewable energy sources, Elon Musk said on Twitter.
His tweet was a response to Magda Wierzycki, CEO of the financial company Sygnia, who accused him of manipulating the cryptocurrency market.
According to her, if it was a listed company, the US Securities and Exchange Commission (SEC) would have opened an investigation and severely punished Musk for deliberately raising the price of bitcoin with statements on Twitter, after which he liquidated a significant part of his position at the highs.
Tesla began selling electric cars for cryptocurrency in March, but in May abandoned it, pointing to concerns about the impact of mining on the environment.
The debate about how bitcoin affects the environment has become increasingly fierce over the past six months. Critics call for mining cryptocurrency using renewable energy sources. However, according to the Cambridge Center for 2020, more than 39 % of miners use renewable energy sources for mining BTC.
Financier Peter Schiff responded to Elon Musk's statement with a mocking post. He again criticized bitcoin and questioned its potential as a means of payment. In addition, Schiff attacked the CEO of Tesla, accusing him of manipulating the market.
