I solemnly swear that I, kakosaro, shall never unbox a Mann Co. Supply Crate until the end of all worlds.

Everyone is trying to get profit. Everyone asks for 2 keys or above (and they have absolutely no interest at all.) When the hype was high, people sold successfully for even 4 keys, as shown here:

http://www.tf2outpost.com/trade/9242393 - sold for 4 keys

http://www.tf2outpost.com/trade/9251306 - offered 2 and 3 keys

http://www.tf2outpost.com/trade/9239995 - offered 1, 2, and 4 keys

…that is not the case anymore.

Offers on trades seem to be going around one key, even if they are lowballing.

Sales on the market are constantly fluctuating, currently at $3 USD

…and classifieds are selling at around 1 key (1.2 keys to be exact, which only one of two links has sold)

If you have your own links as proof or counterproof, they will be greatly appreciated. I will close this upon request if the market is not correct.
