Many coins have been started when Cryptocurrencies were less developed and much less innovative.
And here it is a big problem for many Altcoins: using outdated Blockchain technology.
That is so true, and I would like to add besides the tokens and coins that, you mentioned Doge was on the verge of extinction until Musk pumped it and adopted it, and that started the meme era; the technology and the trend keep changing what works now and what's in now may not work or adopted in the coming months, so be sure to check every coins or tokens that are in your portfolio and be sure to quick to dump or sell when there is a rug pull or the project has been abandon.
If you won't follow the development of the coin or token, do not invest; it will save you money and effort.
