This is minus expected value
Skin gambling adds custody and settlement risk to ordinary gambling loss. An item can change value while it is held by an operator, a withdrawal can be delayed, and the price used on deposit may differ from the price used on withdrawal. A bonus does not remove the house edge or those risks.
You must be 18 or the legal age where you live, whichever is higher.
Before transferring a skin, check the operator's item valuation, custody, trade-lock, withdrawal, KYC and dispute rules. Use deposit limits, timeouts, and self-exclusion where available. Missing controls or unclear settlement terms are reasons to leave, not reasons to transfer another item.
Steam and Facepunch do not back these sites. Steam Support cannot reverse an operator balance or settle a third-party gambling withdrawal.
