a group of rich people in the backpack.tf forums are planing to trade all there buds in for keys then buy every single key (that was selling for low of the price at that time) then they will relist the key AT INSANE prices (while the keys were 5.66 they listed some for 6.33 and when they were 6 listed them at 7) then after since there aren't and sellers selling at that price anymore. desperate people will say "HEY its only one scrap more than the price" then once its bought they will place a vote on backpack.tf saying the key price is achiveable at a higher range THEN they continiously do this one scrap at a time untill it gos realy realy high so they can re sell them after they get to a certain point
