This is minus expected value
If you gamble on skins or crypto, the house edge and the deposit/withdraw spread work against you on every round. A bonus does not flip the math. Only stake money or items you can lose.
You must be 18 or the legal age where you live, whichever is higher.
Use deposit limits, timeouts, and self-exclusion on the operator if they offer them. If a site has no such tools, that is a reason to leave, not a reason to deposit more.
Steam and Facepunch do not back these sites. A stuck withdrawal is not a Steam support ticket.
