There is a ton of jargon and extremely cryptic terminology used in many tokens which that jargon makes the project creators appear too smarter than the investors and that gets diluted in the hype where many people don't critique their flaws or see the problems early on; but only until it is too late.
Education on the basics needs to be clearer and simpler to translate and untangle the cryptic jargon used to blind and manipulate investors. Your proposal is close to that.

This is the problem.
Over-diversifying into a countless amount of tokens and coins isn't really a good idea and they're highly likely to lose more money by doing that. It's better to focus on a very few number of coins or an extremely few amount of tokens that have been around for years or have a valid use case, rather than jumping into thousands of ERC-20, SPL governance tokens that are just all the same but have little reason to exist.
Hence this, I rarely look at tokens. For the long term, it is the coins that have stood the test of time for years that matter and one hint to look out for is regulations. Ask yourself is it realistic for 20,000 coins and tokens to all survive regulations?
If the answer is no then you would agree that not all of them will survive and that the top 30 exceptional coins or a very few selected tokens and the ISO 20020 compliant coins would survive this.
Therefore, there is no need to look at hundreds of new tokens at all. (This is not investment advice) But, please keep building.
