UpgradeGG is a CSGO upgrade gambling system that can up the value of your skin by 1.5x, 2x, 5x and 10x. So, you can for all intents and purposes upgrade your $2 skin with a $50 one. That said upgrading is a gamble, and you will win at random. Each try costs you points, so if your luck is good, you’ll end up with much more expensive skins than what it has cost you to try. Players need to sign-in with their Stream account credentials and then click on the skins they want to upgrade.
