Just thought I would post this calculation to show why I believe GPUC will be a success and will be used by people who haven't even mined any.
I pulled all the figures off crypto-rush exchange about 20 mins ago.
So lets say you have only just heard of GPUC and your balance is at 0
Current BTC price is around $600
According to the front page the selling price of a R9 280x will be $480 which is 0.8 BTC
At the current price of 0.00000029 you will need 2,758,620 GPUC to purchase a 280x
As the price is going to be directly linked to the exchange, as the price in GPUC/BTC goes up the amount of GPUC you will need comes down.
Buy 323,814.75 GPUC at 0.00000029 = 0.09390268 BTC
Buy 137,152 GPUC at 0.00000030 = 0.04114560 BTC
Buy 50,000 GPUC at 0.00000031 = 0.01550000 BTC
Buy 30,000 GPUC at 0.00000033 = 0.00990000 BTC
Buy 100,964.12 GPUC at 0.00000034 = 0.03432780 BTC
Buy 502,354.18 GPUC at 0.00000035 = 0.17582397 BTC
Buy 667,799.73 GPUC at 0.00000036 = 0.24.4.790 BTC
Buy 25,820.54 GPUC at 0.00000037 = 0.00955360 BTC
Buy 35,000 GPUC at 0.00000038 = 0.01330000 BTC
Buy 58,240 GPUC at 0.00000039 = 0.002271393 BTC
Now as you have pushed the price up to 0.00000039 you will only need a total of 2,000,000 GPUC at 0.00000040 to purchase a 280x
Buy 68,853.85 GPU at 0.00000040 = 0.02754154 BTC
So you now have a total of 2,000,000 GPUC enough to purchase your 280x
Where this gets interesting is when you add up how much it has cost you in BTC to purchase those 2,000,000
you will need to spend 0.6636 BTC which is roughly $398 that's $82 cheaper than if you bought from the store directly in $
This is only an example, and once things get up and running properly, there will be more volume on the exchange, and you may only push the price from say 0.00000029 up to 0.00000034
to get you desired amount of GPUC but the same principle applies.
There is a flaw, in that the price will only go up to a level that is equal to the price of a gpu or less. otherwise people will just go and pay for one with cash.. So the price can only go so high any more and people will be throwing away money..
Given that the shop haven't announced any prices yet, still to early, people can push the price as much as they can. The sell order has very small ammount, if mining adjust and keeps going high all the early miners and investors will make a heftly profit. Until the first batch of sales goes out the market is runned by the miners/traders, after that the GPUC Company will have the coins to dump into the market. And for them to make a profit as a company they would have to dump at a higher price then what they charged for the coin so even then the price must go up.
Overall think of it just like whole blackcoin multipool, the shop will make it so the buyorders will always be there and any dumps in price can and will be addressed because of the market.
