Two in-date purchases in the past 3 months. My $19.99 Marketplace purchase (December 3rd 2024) and a mass cash-out between Kolt and drugged out hobo (13th October 2024).

Here’s evidence of the one way trade between Kolt and "drugged out hobo". The one-sided nature of the trade makes it clear it was a cashout: https://backpack.tf/profiles/76561199513453937#!/compare/1728691200/1728777600

My $19.99 purchase was done via Marketplace. So backpack compares aren't very useful. Hence I will provide screenshots of the marketplace purchase and key price at the time of sale:

$19.99 / $1.76 = 11.36 keys. Let's round down to a round 11 keys.
