It's hard to predict since meme coins are just coins with no real use case, if they actually had a use case then we would be sure they would survive, but in this case, they don't have anything to keep the project from dying, they are just fun coins nothing more and in my opinion the only meme coins that will survive for long is dogecoin, followed by shiba inu (I'm not so sure about it though), both are good meme coins that will likely survive even in a bear trend.
So if a meme token has real use case, it would be considerably better than other meme tokens and will be more attractive.
Dogecoin has been surviving very well in many years because it has use cases on gambling sites and not only been used for trading. Some merchants allow you to use Dogecoin to buy things.
SHIBA INU has a long time to get what Dogecoin has. Other meme tokens will probably never get what SHIBA INU has and never reach closely to Dogecoin. I believe more than 90% to 95% of meme tokens will dead after 2021 and 2022.
