ELON MUSK QUESTIONS ASSERTIONS BITCOIN IS SUSTAINABLE

Tesla CEO Elon Musk continues the Bitcoin debate, On Thursday he tried to refute claims that Bitcoin is "greener than critics say." 

As part of a string of tweets Thursday, Bitcoin Magazine cited Kraken CEO Jesse Powell saying not only that the digital currency is green but that Musk – who has recently questioned the digital currency's environmental impact – "has some more studying to do."  

"Based on what data," Musk replied.

To bolster their point, Bitcoin Magazine released a round of back-to-back tweets citing information from its latest article using data from The Cambridge Centre For Alternative Finance.

"The Cambridge Centre For Alternative Finance estimates that 76% of all miners use renewable energies as part of their mix. CoinShares estimates that total share of renewables may even be as high as 73%," the magazine tweeted. 

In recent months, Musk has drawn attention to cryptocurrency, expressing concern over its mining process – the process of creating the cryptocurrency. Bitcoin mining is done by solving mathematical puzzles on powerful computers that require large amounts of energy.
