And there is no guarantee that the project will increase once the bear market is over because only the projects with great backing can bounce back, while other projects will be buried without being able to bounce back. It's better not to take big risks on such projects because there are still other good projects to invest like bitcoin or other altcoins. Besides, there are so many types of meme coins nowadays and it's very hard to find meme coins that can be increased again.
Nothing is guaranteed to last forever. As you've said before, there are good projects and bad projects. You'd just have to choose the good ones by doing your own research. Crypto projects with a proven track record of development and innovation, are most likely to succeed in the long run. The rest will simply go down the drain after the hype is over. There so many "meme" coins on the market, but 99% of them are garbage.
I think only Dogecoin will survive because it's the oldest "meme" coin with a solid foundation built upon it. Neither Muuinu, nor Shiba Inu, nor BabyShibaInu will survive because they're only driven by hype. If they last, it's because the whales want to play with them for a little while. But that doesn't mean you should rely on such coins as a long-term investment. People are too greedy to realize how garbage most "meme" coins are, so they will keep investing into new coins with the hopes of getting rich as soon as possible. It's too bad because that will lead many to become "rekt" in an instant. At least, the competition on the market is healthy. As long as decentralization wins, nothing else matters. Just my opinion
