Conclusion -

Barely 5 pages on OP from which some are in sets, some are killstreak and some are looking for offers. Couldn't find a single trade bellow 3 ref but some buyers have bought at 2,66 and sales still happen at that price so I will keep it in the range. Also there isn't a single escape plan on classifieds below 3. Iunno what is that sudden demand for this thing but it's raising.

tl:dr

2,66 ref - kinda quick

3 ref - doable
