First, you need to take your inventory off private, because it makes you look like a scammer. Plus no bot will trade with you as long as your inventory is private.
Second, with only 1 ref you can't get much on scrap, cheapest cosmetic being 1.44 ref, cheapest strange 2 ref and cheapest skin being 1.55 ref, but if you sell the hat to a scrap bot for ref, depending how much it's worth, you can get the slightly more expensive things.
