Impossible, and it's a fact that you're stating.

Many of the enthusiasts and investors of shiba trying to believe that this is going to happen when the market cap of the entire market grows a lot. It's true that there's the possibility but it won't be shared entirely to shiba.

The biggest share will always go to Bitcoin and the other top altcoins and shiba will only get a slight portion of it. Dogecoin hasn't even reached $1 yet and it was so close there but I don't think that it will reach $1.
