Let's just wait until when this memecoin trend will end, in the end everyone will return to the more trusted Bitcoin.
Yeah, meme coins is all about hype, no utility, no value and no long term property. Take a look at Trump meme coim, when it was launched, many people rushed to buy, those who were early were lucky to make returns, but right now you can't really be talking about buying that meme coin, because you may lose your money.
In the long term, there's a high chance that you will lose your money because after a few years, 80% of the total supply will be held by the developers (assuming that they will not be selling their coins). Just look at their tokenomics.
Short term, you can still make money from it AS LONG AS you're good at trading. I mean if you will look at the chart, it seems like $25 is the current support. I agree with what you said though that most of the meme coin doesn't have use case at all, and it's all about hype, and I believe this is also the reason why Bitcoin is struggling to go up. Instead of the money going into Bitcoin, it's all going to meme coins.
