People who say backpack doesn't affect the market are just straight up wrong

I got this hat back before the switch to keys, so it was priced at 17 keys on backpack. I paid essentially 9 keys for it, and was trying to sell it at 16 for about a week. Somebody else had been "quickselling" at 14 keys for something like 3 weeks, and was getting zero offers. Anyhow, like a day after the currency change, which bumped this thing up to 40 keys I was able to quicksell it for 15 keys (the guy previously quickselling for 14 changed his price to 30 lmao). The guy I sold it to sold it for 25 keys pure in a week http://www.tf2outpost.com/trade/25683347

Anyhow, I just find it hilarious how the converted backpack price being so over-inflated since it was last priced with buds at 19 keys actually did change the value.
