Upgrading skins in CS2 has become a fun side hobby for me, but I was initially overwhelmed by the sheer number of platforms out there. I wanted something clear and easy to follow, and I found a great breakdown on how it works right here: https://csgototem.com/cs2-skins-upgrade/. It walks you through the process, compares top upgrade sites, and even offers tips on how to increase your chances without throwing away good skins. Helped me a lot.
