there is no meme coin that suppose to be next shiba or doge. Although its quiet impossible to predict in my opinion as you told but this is speculation sector! Anyone can predict & share opinions but honestly i don't know any of such meme coin. I've checked coingecko, cmc & some article too but i don’t found strong potential in any meme coin that could be make itselft next shiba or doge. rarely possible to see another such altcoin again
They're both the most known meme coins. As speculators, we'll look for another one that has the same potential but it's hard. The market is no longer the same when those two have flew.
What you're going to see with the meme coins these days are almost the same, you might be discouraged to see them not moving the same way as how doge and shiba soared before.
