Elon Musk is not afraid to speak his mind through Twitter. In May, he tweeted that TSLA stock price being too high - he meant it, despite the fact that the statement will depreciate the stock price (temporarily). In July, he sold short shorts on the Tesla merch shop for $69.420 to mock TSLA short sellers. In early December, he wrote a memo to his Tesla employees to remind them to be conscious about budgeting, because Tesla is not profitable enough just yet to justify for their current stock price. Recently, he joked on twitter that Bitcoin is his safe word, said that bitcoin is as bs as fiat and made a comment about doge (coin). To be very honest, he is just speaking his mind, bitcoin enthusiast or not, the price action has been erratic just like his own company's stock price, his comments are simply reflecting what he believes is true - the man is living life - in the end he means everything he says and he means well.
