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.
