if you really wanna sell them quick - you will need to go first for a couple of trades.
also, to avoid getting scammed, you may want to trade with the people that are on the trusted list - they got their place on that list for a reason.
alternatively, you may want to ask for proof of at least 5 successfull trades, with pic or vid proof.
should anyone on the trusted list want to buy anything from you, i can guarantee that you will have nothing to worry about by going first
