Naysayers have one thing in common; they all are imagining a closed scenario with relatively few players present. Rather, think of the exponential involved when it becomes picked up by 10, 20, 50 000 people at once. The Olympics will create news coverage. Developing countries will prefer the lower cost, hell, we all will. This coin is entering the collective 'nousphere', at least for a short time, and that may be all there is to it, I'm afraid.
The steady production of doge to infinity is nothing compared to the rampant and baseless production of currency by every freaking central bank there is. This means that no matter how 'austere' the fiat markets become, doge will remain relatively deflationary.
