Is there anyone who regularly buys game keys (GMG, etc) for keys?

Note: there is a separate trade section here, and all trading related activity should stay there.

I don't think anyone will take a key and save it for later - too much risk.
You need to find someone who wants the game now, who will activate it and verify that it's legit.

That being said, what are you asking for it?

ppl rarely take steam keys for reselling

• It's going for $27 on G2A, you're selling it for 14 keys which are valued at around $28 if you're talking about CS:GO keys. And if we're just talking legit stores, WinGameStore has it for $29.
• There's no guarantee the key won't be activated already after the re-sale
• You have pretty much no rep

Advice:

• Lower the price. You don't stand a chance if you're asking for 14 keys.
• Build up some rep. You can do this easily by buying/selling bundled/previously free games.
• https://www.steamgifts.com/trades/search?want=hearts+of+iron+iv (these people have Hearts of Iron IV, try getting your desired swap with some of them. Your chances are very small though unless they explicitly wish for Stellaris)

Build trade rep. Nobody would believe somebody under a few dozen rep is selling a random non-bundle game that costs more than 5 USD and the key is actually working (or if it is, it won't get revoked because it was acquired with a stolen credit card).

You should take the advice from those above. Also if you do not bump your trade nobody will see it. Normally games of higher value take weeks to get a buyer (even when it is a decent deal) with constant bumping of the thread (at least a few times a day). Games that are sold quickly normally are cheap games from bundles or games that are vastly under market price

u can always sell it on G2A, wait 14 days for the money and buy keys there.(although the key prices change every day)

37$ = 33.54$ after fees.
which can net u 16 keys worst case.

not saying that's the best option , just worth mentioning.

The bottom line is, your key is worth what people will pay for it. If people wont pay 14 keys for it, it's not worth 14 keys.

the game is allready self in the nova edition 29 euro so really not worth to buy it with that risk from a stranger for 14 keys. And its paradox in less then 3 month for 50 % avaiable
