"Unusual" disappearance

[EnviableToaster]

So I wake up in the morning only to find out that my disco beat down dead cone is nowhere to be seen in my inventory. After a small investigation I came to an dead end. After looking at my trading history, there's nothing showing the item leaving my inventory and I have never received or sent any trade offers regarding this item. 

Further more, the item history indicates that the unusual is untraceable:     

 

As I said, nothing seems to indicate the item being traded away and it has disappeared around 4 am so I couldn't have deleted it by accident or something.

 

I really enjoy trading and I have taken the time to look into the common ways of getting scammed, I haven't clicked on any malicious links or anything like that. A few details maybe worth mentioning is that this user: https://steamcommunity.com/profiles/76561198279777031 seemed to be interested in my item, but removed me the same night it disappeared maybe before or maybe after the disappearance idk. He never acted really suspicious, but I still asked him if he could've had anything to do with it (I'm waiting for a response). The item was also listed on the scm and it still is (should probably remove it).

 

That's all I could come with... are my other items in danger? Could this have happened to anyone else? Should I contact valve about the issue? I hope some of you could help me have some closure and hopefully we'll all learn something from this bad experience. Thank you all for your time and help!

When you list an item at SCM, it disappears from your Inventory, this is normal.

Oh I never noticed that, I certainly feel dumb but mostly relieved. Thanks for your help!
