NEM's current problem is that it hardly produces news. Behind the scenes there is hard work being done on Catapult which will drives the prices as soon as it has been released. Until then the price will probably hardly move upwards. In my opinion, it is more important that the team focus on the development of this important milestone and not on short term price increases.
XEM -4% in Poloniex.
In the last 2 days there were couple attempts for a rise but they did not last.
Anyway the volume in "drop" is quite thin, like indicating that
a) there is not any big consensus about the direction - maybe some want to drop the course.
b) new buyers are waiting.
Why would anyone sell now, when there has been 2 days quite peaceful period, kind of waiting a new hop to a new peak.
