As far as Elon musk is concerned, i think he tries to manipulate the market for his own good. He makes tweets accordingly and then buy or sell. So he has nothing to do with hype. His intentions are now kind of exposed to the crypto community and not much effect his tweets make compared to the initial impact.
Honest question dude, do you really believe that a guy with a net worth of 180 billion dollars in the pockets is going to manipulate a meme coin to then buy or sell on an exchange that got him registered with KYC, risking to be sued for market manipulation as a manager who is behind Tesla and SpaceX and many other companies?
Come on, you can't believe that yourself. Do you think Bill Gates cheats when he plays poker with his friends to win the thousand bucks in the middle in the end?
