It is underpriced in that it generally costs more to make QRK than it sells for, but I think it's a PnD that's already on it's death throes due to lack of support from merchants or any use.
How much does it cost a botnet to produce 1 QRK? Remember stolen computing power and stolen electricity = 0.0000. CPU coin = botnet coin. Whatever you can produce with a single CPU the average botnet can produce 10,000x as much at near 0 cost. It never had a future.
You do realize it's possible to do the same with GPU's?
Utilize the GPU of every PC that is part of the botnet?
I mean a company already did it with bitcoin within their software (too lazy to google now)..
