That's a great point too. I cryptocurrencies deserve a classing system better than just "altcoin", "shitcoin", and "memecoin". There's not really an official or unofficial grading system other than these terms and vague terms like "utility token" that help to differentiate one cryptocurrency or token from another in terms of quality, which is a problem.
Here, I got you covered:

But to be more serious, 99% of the other coins would just be dumped into the "Shitcoins" category.
Based on total coins and tokens deployed, I'd argue that even more than 99% would belong in the shitcoin category

While the evaluation is inaccurate (from my perspective, something like Uniswap's token that represents governance of its decentralized product ecosystem (including the uniswap decentralized exchange, being the flagship product that generates revenue from trillions of $ in fees from volume), a visual like this would go well with a framework with conditions that properly evaluate a cryptocurrency/token that doesn't fit in the shitcoin segment of the market.
