Is Musk the boss behind SHIB?
Is there an advantage in the future? I am optimistic that SHIB's performance is as good as DOGE

Can someone explain, thank you

What makes you think so ? I dont think Elon is the one behind SHIB.
He tweeted DOGE indeed, but that doesn't mean he created another dog coin.
I think SHIB performance is good because it is the first dog-meme coin that runs in smart contract blockchain.
I also wonder why anyone would think that way now, when it's pretty clear that Elon Musk has a lot more work to do than thinking about dog meme coins that just end up being a joke in the end, even if he does tweet at times to one of those memecoins, that doesn't mean he is behind it.
