CSGOupgrader offers players an incentive to upgrade their weapons and skins on the website with a $0.50 bonus after the first upgrade. Additionally, you can also qualify for up to a 6% bonus. Players can choose the weapons they want to upgrade. Then select the multiplier. So, you can upgrade to 10x the value of the skin you choose. If luck is on your side, the upgraded skin is yours, but if not you’ll lose the skin you put up for the trade.
