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.
I agree with you, people need to use the coin. We need to expand past just selling GPU's though. As I stated on an earlier post, GPU prices are starting to decrease, the market isn't as strong as it was a few months ago. By selling gift cards cheaper etc we can create a demand to a whole new different population, not just those who are seeking GPUs. That's where the GPUcoin supporters can come in and use their connections and see what they can bring to the market.
I think the marketplace is great, but it needs to be expanded.
Everyone's ideas are awesome, I sense that people that are still left in this forum and thread want this coin to succeed.
