Let me get this straight Green paint cost 1.33 metal. You can sell it in market for dollar a piece. 1.33 x 3 = 4 refs (same as one key). Key cost 3.66-4 refs. You can sell it for 2 dollars a piece in the market. So would you rather pay 2.66 (old key price btw) for 2 paint cans, than pay 4 refs for essentially the same exact outcome in the end?
Actually it's variable from 1 ref to 1.33 refs, but i'm pretty sure your comment was an incentive trolling in favour of the owner of this trade. So does everyone who openly agrees with this preposterousness.
look, key prices aren't going up, ref's value is going DOWN. It's just inflation. Since weapons are constantly being spawned, there is more and more refined metal out there, and it, in itself, is qutie useless.
If that was the case, then craft hat value would fall down as well, which it isn't. People are just inflating the price of keys to inflate the price of keys. Eventually it's going to crash when nobody can afford them anymore (5 ref is my guess) and then it's hopefully going to go back down to 1-2 refined
