The Basics:Įvery skin is CS:GO is assigned an exterior float value as well as a quality (rarity). It represents what I personally believe is best from my experiences over the past 4 years doing hundreds of trade ups. Throughout the guide, I mention a few websites/programs/YouTubers, but none of this is sponsored in any way. This guide includes everything from barebones knowledge, up to more advanced details. My goal is that even if you have, you still might learn something new. Feel free to skip ahead if you have done trade up contracts before. In this guide I will talk about everything you need to know about trade up contracts.
