So im guessing your steam items skins which you wanna bet gets converted into coins.
What are 'skins'? Can I buy them with the $5 in my account? Or do I have to buy and play a steam game first, and somehow find the skins in-game?
go to steammarket an buy any item, but you won't be able to use it for gambling. you will need to enable 2FA and then wait 7 days untilyou can send it away.
