Conclusion: Before you say something stupid like "Not enough proof, downvote", take a look on the market first. This thing is so rare now. Demand > Supply because supply of craft hats went down and it's reasonable for this thing to rise. I don't remove 1.33 because there are some 1.33 sellers on the market.

Feel free to counter / support my proofs.
