That's correct and that made him safer as he has no responsibility at all, a billionaire expressing his opinion on DOGE in a positive way will always gain the attention of the people, and it happened, DOGE was hype and it pumped like crazy, so now Elon can leave this as he already made a lot of money during the bull run.
That is Elon Musk's target in general because he must be aware of that very well where once he has enough advantage on Dogecoin, he can leave it at any time by not telling anyone, so this needs to be understood very wisely, because basically Elon Musk has done nothing wrong with that, he just has more abilities that no one else in the crypto space has.
