Well, the "1 PND = 1 USD" is more of a metaphorical matter. I would be very happy with 100 PND = 1 USD in a year or two, but even this seems to be a little exaggerated.
Price variations are to be expected, one must look at the mean value on more than a few days or even weeks in order to asses the success or the failure of a coin.
To really succeed in implementing the dev's stated vision, PND must become a real currency, with a relatively stable value and widespread adoption and use. The current "comodity" status is just a phase. The take-off phase, hopefully

I have no doubt that this coin will succeed in the long term.
I'm worried about how people will react in the short term, and how good natured folks will screw themselves over at the will of ill-willed individuals who would wish to extort others and spread FUD to hurt others and gain profits for themselves.
But in the end, I know what will happen if I hold. I know what will happen if I put my trust in these devs.
