Demand for the cards is going up as the supply goes down. F5'ing the first page of a card and they are all marked as Sold!, which shows the rate at which they're being purchased.
This also happens in short term fluctuations. As cheap ones get snatched up, some people will buy at higher prices. Then, cheap ones come back into play.Ilúvatar;95727712 said:Steam card prices follow a U-shaped trajectory during sales. When they are first released, they are posted at artificially high prices. As more people post them to the Market, everyone keeps trying to undercut everyone else - so the price decreases. At the end of the sale, these artificially cheap cards are purchased at such a rate that the cards posted earlier become the cheapest.
An unfortunate byproduct of them being forgotten about, I think.But those more expensive cards wont all be sold. They will die. 200k cards are going to die because people wont lower the price.
