Well if they are smart bagholders they will try to keep the price low now, let's say under 20 sat, do microtrades and buy as much as they can while mining it then when the store openes up push the exchange price to a very high value, let's say 200 sat, so they can purchase more items for their coins. Repeat that each time, at least the first few times, then the store could counter it with microtransactions from the coins they got for the items. Just my logical view on what will happen.
Would you like to explain why someone would pay substantially more for the coin compared to what it costs to mine it? I understand things might change once all the coins have been mined but that's little further out. A few posts back we heard that it's profitable to mine at 20 sat so there you have the market value of GPUCoin?
At the current price of 20sat one would have to dump 325m coins back to market to buy 100 new display cards at 400usd each.
The interesting part of this equation is where the 100K USD per month comes from. It does not directly come from people mining the coins since they just want to change to coins to GPUs and have already given their payment to the electricity company. It has to come from people buying into cryptocoins to create the monthly 100K that then exits to the display card manufacturer.
In other words, it's like people would be allowed to print their money at a small cost for a certain time. As long as it's possible to print money people won't pay much more than the cost of printing. It all changes when you can't print the money (GPUCoin) anymore. The GPU factory/wholesaler won't take this printed money (GPUcoins) so the storekeeper has to exchange it somewhere for real money. The only way to do this is to sell the printed money back to the people who printed it while they keep on printing more - and they for one won't be paying a premium on the self printed money returning to them.
Interesting times we live :-)
