Learning about those layers helped me avoid buying skins blindly. At first I thought rarity only depended on the color tier in the case, but the market clearly reacts to more details than that. I started reading about pattern variations, float ranges, and how case drops influence supply. While searching for explanations I spent some time reading articles on
https://dmarket.com/cs2-wiki/ cs skins wiki and it helped connect all those pieces together in a clear way. The pages explain how float numbers work, why some patterns become popular, and how skins enter the market through cases. After going through that information I began evaluating skins differently. Now when I look at an item I think about its float range, the case it comes from, and how common that case currently is before making any trade decision.
