Here we are again with your "centralized crypto index".
NO ONE IS FORCING YOU TO USE COINMARKETCAP OR ANY OTHER SIMILAR ALTERNATIVE.
You yourself can freely judge a project by it's use-cases and fundamentals without looking at the price; and you can freely use all these coins/tokens regardless of what it's price is. Your complaint/argument doesn't make any sense at all. Shitcoins are called shitcoins because, well, a lot of the coins/tokens are really just either a scam or useless! People aren't calling other coins/tokens "shitcoins" just because they're holding bitcoin.
