Twitter staff locked down Elon Musk's account when he responded to someone to 'buy bitcoin' because they thought his account might have been 'hacked' haha

His tweets have been accused of wiping value off of Tesla's stock prices before, I wonder if his words carry enough weight to effect crypto prices too
