https://backpack.tf/item/14052677149 Seller at 20 keys for a month

Sales at 14, 15, 15, 18, 24

14 was a dump and 24 is high given the unsold at 20 that has been there for a month. Gonna keep 15 in the range despite buyers at ~15 since there are 2 sales at that value indicating it's a common trading point, and buyers weren't that high at the time.

Going with 15-18 keys
