At this moment, there are 3000 CS:GO keys in bot inventory and very little TF2 keys.
Many of my customers are unable to deposit keys.

Here is my 2 cents about the exchange rate:

Breakout, huntsman and Phoenix : 1.08:1.10
Falchion, Chroma, Chroma 2, Vanguard, Esport, Winter : 1.07:1.09
Normal CS:GO keys : 1.05:1.07

From the begining they made Vanila keys at same rate as good keys , now theres is 1500 + vanila keys and no one wants withdraw them for this ratio
