Yeah you’re right. Also the thing in TF2/steam is that you don’t usually profit from opening crates because the chance of getting an unusual or a very high grade cosmetic is very low, it’s basically a bet. 2.5 dollars for a key, and the crate you opens containts a 1,22 refs cosmetic (keys right now are 87.11 refs, that’s about 0.035 dollars.
Holy Satan, last time I checked keys they were 60 refs (yes it’s been a while), fricking inflation.
