Your solds at 2 buds look like quicksells

that 2 buds sale; Lucifer and Karkki Katu seem to be either the same trader or 2 traders sharing unusuals given how all 3 unusuals in that trade change hands between the two accounts.

the 2 buds quicksale is as you say, a quicksale. the 2 buds seller is also, as you say, young. Not convinced 2 buds belongs in this range.

If this sold for 2.2 buds, explain why 2.2 buds isn't in the guy's backpack.

SOLD for 2 buds? To the previous owner, who coincidentally decides to quicksell at 2 buds again?

Your evidence points nowhere to me. Downvote.

your "seller" at 2 buds is actually 2.5
