These coins are either dead or defunct. And in the cryptocurrency sector, it is very rare to see coins that have been dead for so many years being revived. The promoters of these coins have moved on to other projects, and other developers are not interested in them because there is no premine advantage for them. In short, it is not like investing in stocks that have fallen by 99%. With stocks, you can say that there is still a 1% chance of getting revived. But with dead coins, the chance is like 0.00001%.
It's fair argument. Most of the old coins tend to become abandoned by developers as they move onto the next big thing in crypto. Nowadays, it's all about "De-Fi" and NFTs while old coins are being left behind in the dust. The only exception would be old coins like Bitcoin, Ethereum, Litecoin, and Dogecoin. These coins will survive in the long run while the rest will go down the drain. I'd suggest anyone to put most of their money into new coins, while putting the rest into prominent old coins on the market. That way you'd minimize risks as much as possible. New coins are highly profitable in the short term, but most of them usually disappear over time. Only a few manage to survive because of their communities supporting them every way. What's important is Blockchain technology above all else. As long as Blockchain is alive, nothing else matters. Just my thoughts
