Exchange won't matter. Lifeblood is in the flow of the product off the shelves, and the restocking. People need to be using the coin. I realize this discussion is coming from people not having enough coin to make a purchase (at least, some folks), but there are folks who do have plenty of coin and are simply holding.

To be honest if you look at the price in the store and upvert it to USD, it's a good deal on many cards. I'm surprised someone isn't simply buying GPUC, buying the cards, and then reselling.

I'll be honest, I've considered doing that since I can pick the cards up from GPUCoin himself.
