Honest limitations
CardZ Marketcap is not designed for tracking ungraded cards or collectibles outside of Pokémon and One Piece. It exclusively focuses on PSA 10 grades, so it won't provide data for other grading companies or lower PSA grades. The platform's scope is highly specialized, making it less suitable for general trading card market analysis beyond its defined parameters.
