I still think it should rise, as it should almoust be impossible to mine it (therefore no everyday miners dumping)..
.. but well, maybe logical to me is not logical to others..
First there should be demand and there's not a lot of that at the moment. When it was being traded (and of course mined), supply and demand was there so it was fluid for some time. After the miners left, it all went downhill from there and the speculative demand left along with them. You can just see it from the exchanges, the bookings are getting thinner by the day.
Being speculative of course, makes things a bit unpredictable. Anything can happen I guess.
