Basically nothing is certain, i guarantee anyone will not know how long memes on the solana network will remain alive, all just assume. i think as long as people continue to introduce meme tokens with all the benefits they get in a relatively short period of time, new people will continue to come.
Plus donald trump just created a meme token, this adds more fomo so many of them will buy in, adding to the long list of meme tokens especially on the solana network.
That's why they are "meme" coins after all, nobody would know anything about all of this, it's just not a reasonable approach at all. I get that you may feel like you want it to do better, but that doesn't mean that we are going to end up making a lot of profit from it neither, we can't do that, it's just not viable at all.
I understand there are people who wants to invest into memes and they like doing it and they think it's fun and there is a chance of them go up so they want to ride that trend wave. However, just because you want to, doesn't mean it's a smart decision, so we need to realize that it's just a danger awaiting the market and we are unfortunately just waiting to see who will be impacted by this on the long term.
