I said it before and I'll say it again, this entire trading economy is SHIT, it's just a simple cash cow for people wanting to make enormous amounts of profit. Trader Empire, aka Spreadsheet was taken down because it grew too big and everyone quoted it, now backpack.tf has taken it's place, and yet no one is complaining because of it's obvious greed driven, but flawed transparency, something that all the idiots don't seem to realize. Well, I hope they enjoy the rising prices, because while it was one of the leading factors for high amounts, it will not be the sole reason that prices continue to raise.
TF2 was first, then DOTA 2, eventually we'll be seeing CS:GO join the future, yet nothing will improve, with all the money exchanging hands and being spent on pixels, it's going to keep getting worse and worse, until something puts a stop to it, which what that will be, I have no idea.
