TF2 trading was its own beast, having its own currency with metal and all and such.
Too bad that market got so inflated, I remember when keys were 2.33 ref.
The CS market is just skins for skins really.
For the record a Titan Holo from a Kato 2014 capsule goes for 140,000 USD right now and an IBP holo goes for 70,000 to 150,000.
