Heeskane's info:

Quickbought for 30 keys pure and now sold it for a DBD Rebel Rouser + 15 pure https://imgur.com/a/NPLlhbB My b/o was 40, will probably cap at that

Foamy's Info:

The tree will be updated to 42-44 (43), and with the new sales in the comments, this can be 40-43

https://backpack.tf/suggestion/5b451633cf6c75108813390c (see my comment here; the bottom part). it's basicly going to be the same mini as you have.

Going with 40 - 43 keys.
