You can recharge in the steam mall to buy games. There are also some online games where you can directly use krypton gold to buy props. You can also trade cards through the market. However, the market role is limited. Then recharging 30 yuan on steam can remove the restriction. Is it limited?
New users need to spend 30 yuan in Steam and wait for one month before market restrictions are lifted. New devices need to wait seven days before they can be traded again. At this time, you can choose to trade through mobile Steam. Games purchased as gifts must be available for 30 days.
