IMO, I believe this case is just a form of harassment and has no merit at all because it's hard to prove that accusation. first Elon Musk has not directly told everyone to buy Dogecoin because it's a good investment, the second reason is I believe that everyone can tweet/say and shill any coin at any given time because it was a basic right of everyone as freedom of speech so it means just by tweeting a particular coin can be considered as a crime now. Im not a lawyer but I believe this case won't prosper.
