No, coins like that will just be trash in the market and no one will be interested in the future because Hype always changes, every cycle there is always a new face that brings big fomo on that kind of coin, so forget it and don't think about investing in the long term
Your post is ridiculous. DOGE is older than almost every shitcoin that you hold, so that is false. You probably don't even know that Dogecoin is 12 years old already, older than Ethereum? Hype that goes away, sure sure..
And do you think Dogecoin will reach $1 in the future? Are you as optimistic about Dogecoin's growth as before? Without Elon Musk behind it, Dogecoin wouldn't be as hyped. So this is also worth considering. The hype is essentially dead, even if it's been around for quite some time.
As for whether it will still be around in 2030, it certainly remains. Will it remain at the same value/level or be able to significantly improve compared to today?
even almost all altcoins are like that, not only memecoins but other altcoins that have a vision and mission as well as good fundamentals have a high probability that by 2030 their technology will be obsolete and relatively consumers in the market are looking for new, more revolutionary alternatives\
You are comparing things which have nothing to do with each other.
If you understand market theory, technological revolution/disruption, and system adaptation, you'll understand that it's all on the same page.
