Once again, Elon Musk proved that his word weighs heavily in the crypto arena. This time, the tycoon declared that his company Tesla sold about 10% of the Bitcoins he owned and that he will accept them again as a form of payment when there is a more ecological way to mine them, which caused an immediate increase in their price.

It all started when Musk replied to a tweet where he was accused of manipulating the price of Bitcoin. 

"This is inaccurate. Tesla only sold about 10% of the holdings to confirm that BTC could be easily liquidated without moving the market," wrote the CEO of Tesla on Twitter at 12:42 p.m. on Sunday (GMT-5, Central Mexico time).

"When there is confirmation of reasonable clean energy use (~ 50%) by miners with positive future trends, Tesla will once again allow Bitcoin transactions," he added.
