For me personally, the cost of this safety is inconvenience. This, bundled with additional security measures Valve has put in place are a good step forward in that they make Steam more safe for its users. As most of you know, the value of each card can fluctuate wildly in that amount of time.

As someone who is unable to use the mobile authenticator, having trading cards put on hold for 15 days prior to being listed in the market makes the proposition of selling them a difficult one.

In light of the upcoming Steam Marketplace changes next week, I’ve decided to discontinue working on and supporting Steam Idle Master.
