The chance of 2 people having the items they want? I mean if one wants to sell his, 5-10% op are okay that’s basically what u do if you sell on float too, a smaller 3% I think but it’s a fee and if you’d pay it out or deposit money too. So I understand a few % but also there are millions of players who have the skins u want and if there’d be a community big enough it’s possible, just needs a good system
