I own one (so I'm not going to vote on this - eventhough I'm not selling mine). If I were to sell it, I wouldn't take anything under 3,5 pure.

That said, I don't really think your suggestion is right. I got mine for an orbiting fire beak and a bud (over 4 buds in total).

I see two offers of 3,5 pure which is not taken. Someone offered a nnb TC: 4 buds right there. Other offers including unusuals are burning handle (~3,4: "low" according to seller), g. energy bloke's bucket head + max (~3,7).

Also, this is definitely not a bud under green energy.

Those are some mighty old trades. If it can't fetch over 3.5 in that many months, then I guess we gotta accept that as the price.
