Dogecoin had been around more than a decade, and the year 2030 is not very far from us anyways. I am very confident Dogecoin will be around with us in 2030 and beyond, just for their historical value and fast transactions Dogecoin is the staple of memecoins and the most reliable one.
SHIBA and PEPE will also be around in 2030, but their volume will not be as big as the volume of Dogecoin.
I personally consider Dogecoin to be the king of memecoins and the one which is more worth it to hold and pay attention to, their community and "investors" seem to be committed to pump it's price up to one dollar... Which is something very unlikely to happen to be honest.
Fun fact: Dogecoin is the only PoW-based "meme" coin (AFAIK) while the rest are simply tokens living within existing blockchain networks. In other words, DOGE has its own independent Blockchain, while "memes" such as PEPE, SHIBA, and BONK don't. This increases DOGE's chances for survival in the long run. Not to mention, fees can remain low due to reduced blockchain bloat. Token-based "memes" like the ones mentioned, are subject to the underlying Blockchain's network performance. So if ETH is extremely-congested, gas fees for such coins will skyrocket like crazy. Same goes for parent chains such as Solana, BSC, and the likes.
2030 is just 5 years away, so odds are the coins mentioned by the OP will still be around with us. But I can't say the same for the next 10-20 years. Crypto land evolves fast, so anything can happen by then. Just "stick" to diversifying your investment, and there should be nothing to worry about.
