Oh god, here we go again! People are always asking ridiculously high prices for botkillers because there are idiots who think they're getting a good deal. I've seen Silver botkillers go for double their price. People sold for 6 keys when it was worth 4-5. They sold for 7 keys when it was 5-6. And now when it is 6-6.5, most people are selling for around 7.5 keys. See a consistency? They try to always sell it for above backpack price, they always succeed due to noobs, and when the price rises, they up theirs even more. So many vicious cycles exist in this economy. I'm pretty much downvoting everything that uses things related to vicious cycles, because those cycles are destroying the economy.

Would be better if you would post some proof, not only the links to the wrong suggestions
