There have been numerous allegations that Elon Musk sold bitcoin to prove liquidity, and this led to the sale of 10% of Tesla's assets.
But Elon Musk denied the claim, saying that he had not sold any of his bitcoins, and that Tesla had sold some of its bitcoins in the first three months of the year & earning $ 272 million.
Words are words as that and you can not trust his words if you can not verify it.
If you don't know where Elon and Tesla store their bitcoin (in whatever bitcoin wallets, addresses), you can not judge anything from his words. The saying from Elon Musk is matched with what he and Tesla emphasized when Bitcoin is adopted on Tesla as payment method to buy Tesla products. I can believe in their words somewhat, not completely.
The news shows that Elon Musk and Tesla have chosen a large amount of bitcoin as their capital, and by accepting bitcoin for their own transactions, they are launching a bitcoin revolution.
Revolution for Bitcoin because of Tesla. No, I don't think it is the case for Bitcoin. Tesla is not the first and is neither the last nor biggest company have investments in and adoption for Bitcoin.
