I don't think that any other meme can cross market capitalization of Doge no matter how much success that meme gets. I personally believe that Doge will always be king of the meme coin world and no matter how much success a new and better meme coin gets but it won't be able to cross Dogecoin or any other popular coin.
It is true that there are no other meme coins possibly to surpass Dogecoin's market caps anytime soon. Dogecoin market caps is $14,256,673,962. Another meme coin market caps that comes close is Shiba, but that's still around $7,820,005,800. It is just a half of Dogecoin market caps. Sure, even if there are other meme coins looks very hype now but the market caps won't surpass the market caps Dogecoin.
It is difficult for any meme coin to be able to approach, let alone surpass Doge, with its current ranking in the top 10 on CMC. Of course, it is proof that Doge is very popular and has been the target of meme coins for a long time.
Even so, the community should continue to push for Doge to be able to at least reach its old ATH because with its current price of around $0.09, it will be very difficult to achieve it, whether we have to wait for Elon, of course not. Hopefully when Bitcoin increases, Doge will be able to do that too.
