XPM difficulty keeps on trending downwards and devastate the confidence of miners and investors. Now it is fighting for its survival.
Is the difficulty trending downwards? I think it has stablized at about 9.865. I'm worried that the exchange rate is low, but then so are most of the alt-coins. I say hang on in.Again the issue of 'what is significant change in difficulty' comes up.
Look at the difficulty over roughly the last 20 days. It is showing variation but that variation is VERY SMALL at most 9.86 +/- 0.01. We are only talking +/- 1% over in the difficulty 9 range. You wouldn't care if petrol / gas prices raised or lowered 1%... or if the price of milk or bread at the grocery store varied by 1%. We can assume primecoin diff is stable. The oscillations seen when the y-axis of that graph is showing a small range are not significant.
