owh so 1 key is how much worth for you?
I'm one of those who will not purchase a key so my opinion might be biased. Most of the people I met in game who kept buying keys to unlock crates are those who are hunting for hats.
Basically, if you have 3 refined metals & 1 crate, this is what you can get if you craft the metals for hat:
3 refined metals = 1 random hat + 1 crate.
If you trade away the 3 refined metals for a key, this is what you'll be left with:
Either 1 of 7 weapons, 5 hats, a name tag, 4 paints, a duel & 2 unusual items. Worst case scenario, 3 refined metals = 1 equalizer.
