unfortunately, until either Yobit decides to fix the PX wallet and bring it back online... or someone finally makes arrangements to have this coin traded on another exchange, there's nothing that can be done.  It looks like there's a desire to not approach any other exchanges until Yobit gets their wallet repaired.. I'm assuming this is because people have their coins trapped in Yobit land and the developers think this is somehow keeping things fair.. unfortunately, what I don't think has been taken into account is that while everyone is sitting around waiting for Yobit (who obviously has no interest or motivation) to repair the wallet, this coin is very quickly losing its support and anyone that stood behind it.
I for one won't mine this coin again.  Why would I?  What's the point in mining (or even owning) a coin that you can't trade or sell.  It's a dead currency at this point and sadly no one seems to care.  It's too bad.. PX could have been a good thing.
