That's like trying to buy beanie babies after they already had theor run and now they are cheap again. They took off in 2020 because that was the fad then. Most times history on fads don't repeat. Amd then second there are now 9 zillion of these things most of which are all useless scams. Let's just say more millions will be made than lost this go around.
the classic cycle of meme coin, being created at first for the dev to accumulate, then some random whale suddenly pumps it, people interested in it then the price sky rocket, then suddenly price dumps because the devs and the whales are dumping their coin making people as an exit liquidity, its always like this but people aren't getting tired being tricked as such anyway, so many people still trying so hard to be that one lucky guy that happened to buy at the very earliest by random encounter.
but honestly considering as you said there are simply too much of such coin, I don't think random encounter of good meme could be happening as frequently, we can be investing in 1000 meme coin and all of them just gonna flop, since there are still millions of them left uninvested which might or might not be having good market capital in the future.
The devs are even luckier if a whale picks up their coin for manipulation but there are also lucky investors who can get on time before the coin dies. These are the ones that can try again and may only stop once they already experience a massive loss.
Yes, there are lots of these coins now, so that can actually mean that investors has more chance to earn and get rich than ever. There are no such thing as good meme coins, but maybe if they are like the coins that we talk about earlier, that classifies them as one, and also if they will remain to get listed and had some nice liquidity like on what we saw with Dogecoin and Shiba inu.
