Estimates weight each skin's price by its float range and StatTrak chance, on the published CS2 drop odds. Any single open still swings on the exact float you roll — over many opens, the house edge means you should expect to lose money.

Each skin's value is estimated across all wear conditions — weighted by its float range and blended with StatTrak — rather than a live quote for a single listing. Drop odds follow the published CS2 container rates. Expected value is what an average open is worth across many openings; individual results vary widely.
