One of your outdated coin though, ADA is still on the top list of altcoins and making good grounds in the last 2 years so I don't know how can you call them outdated. So we can't say that some coins are outdated and overvalued when they are in the top 20.

So your argument is flawed in the beginning. How about new coins in your list and let's say moving forward 3-5 years from now, will they be outdated as well? And there are some outdated coins still in the market but they are undervalued. So there is no formula here, depends on how crypto people are going to support new and innovative coins.
