I'm not sure if Elon Musk is behind shiba because there are so many millions of people as cryptocurency users and traders. However, it was Elon Musk who once made a tweet and he is so well known to the public that many people assume that the rise of several altcoins including Shiba has something to do with Elon Musk. Even though Elon Musk is only a wealthy merchant, that doesn't mean he's behind Shiba Coin.
