Smiley noted, but I feel I should respond. I have zero knowledge of what drives trading beyond my own activities and those have been very light since the OTC wrapped up. I think other than yours I've only done one other trade on this coin in the past week or so, possibly two.
I'm not involved with any of the web exchanges either, other than trading on them. My response about polo withdrawal issues was from my own experience.
Regarding the dump, I've always said that the coin value needs to find some equilibrium. That may be lower, even quite a bit lower. Right now the reality is this coin isn't useful for anything other than speculating on how it might be useful in the future. That doesn't necessarily anchor a lot of value.
