Alot of players are paying 2 keys (5 refs) for it

Except the fact that botkillers exist mean that normals become less expensive because unlimited amounts of them can exist, they're no longer limited by the amount of crates left.

besides just today 2 new series of botkllers have spawned, so i think it will suffer greatly in price again

Something to keep in mind is that, while it may drop in value a little bit due to botkiller stranges it will still likely retain some of it's value from people who don't want any of the (imo very ugly) botkiller versions of these weapons.

I'd expect it to possibly drop some during the short-term however long term this strange will likely rise back up. (Provided it doesn't appear in any new crates anytime soon.)

tl;dr: Not voting up but I can definitely support the OPs argument.

I have sold many within this price range, 4 ref the most common but a few at 3.66 on trade servers. Voted yes.
