His statements on the future of crypto and disclosures about his ownership of digital assets often boost the price of dogecoin and bitcoin.On Tesla’s earnings call, Musk said the primary reason for the sale was uncertainty about lockdowns due to COVID-19 in China, which have created production challenges for the company.”It was important for us to maximize our cash position,” Musk said. “We are certainly open to increasing our bitcoin holdings in future, so this should not be taken as some verdict on bitcoin. It’s just that we were concerned about overall liquidity for the company.”Musk added that Tesla did not sell any of its dogecoin, a meme-based cryptocurrency that he has touted.Tesla accepted bitcoin as payment for less than two months before stopping in May 2021. Musk has said the company could resume accepting bitcoin once it conducts due diligence on the amount of renewable energy it takes to mine the currency.Bitcoin has been in recovery mode so far this week, in line with the stock market, as investors appear more optimistic about the U.S. Federal Reserve’s ability to rein in decades-high inflation.Register now for FREE unlimited access to Reuters.comRegisterReporting by Hannah Lang, Gertrude Chavez-Dreyfuss and Nivedita Balu; Editing by Marguerita Choy, Richard Pullin and Richard ChangOur Standards: The Thomson Reuters Trust Principles.
