They are kind of rising, but there should be a 10-11 Key range.

Price is going down? I'd say they're only going up. Hype for its stranges and the crate itself are pretty high because it's going to stop dropping soon. That can only increase the rarity and price.

If it stops dropping then it will go up, not before it stops
