Skin gambling
In video games, skin gambling (also known as skin betting) is the use of virtual goods, often cosmetic in-game items such as "skins", as virtual currency to bet on the outcome of professional matches or on other games of chance. It is commonly associated with the community surrounding Counter-Strike 2 (the successor to Counter-Strike: Global Offensive), but the practice exists in other games such as Electronic Arts's FIFA. Valve, the developer of the Counter-Strike series, also runs the Steam marketplace which can be interfaced by third-parties to enable trading, buying, and selling of skins from players' Steam inventories for real-world or digital currency.
