Well I don't think so, although elon musk was so known by his wealthy. He isn't the one who controls prices of tokens especially shiba inu. However he might have something or knowledge beyond fluctuation of it maybe a little bit but not totally a whole thing that elon musk is the one who controls it's price, like some other people says that he control prices through his tweet that sounds like funny.
Elon Musk has created hype in the market through his tweets and various statements, and that has greatly influenced the market price of some coins. Because elon musk has the power to influence a community. I observed everything that happened this year by elon musk's tweets and other things. Although Elon Musk says he doesn't have a shiba inu hold, I've seen him tweet about shiba inu a few times. Now if he is thinking of somehow getting himself involved behind shiba inu, I don't see anything surprising there either.
