I know you guys are hurting; I was too, while the dumping went on and on and on. Let's be honest though, PND is over. It was a nice project and it would've had a lot of potential of the devs hadn't fled (some without a word), but now it's done. You guys can continue to hope that a rise will come about just enough for you to cash out and lessen your losses, but its probably going to be removed from bittrex eventually from lack of volume and then it's only a matter of time before other exchanges do the same. I'm sorry guys.
I was able to move on by moving to a new coin. I would like to interest you all in Bytecent. It's different than many many altcoins and has already been around for 4 months with new developments being discussed all the time. AND this dev takes action; he doesn't just talk, he accomplishes things. It works through Proof of Miner (POM) and not only can you mine with your everyday CPU simply by entering a captcha, this coin can ONLY be mined with CPU! Even if you have an older computer with a slower processor, a community member recently released the beta to a "joined mining pool". It combines the processing power of anyone who chooses to join to mine blocks and divide it among the miners. and this doesn't hurt solo miners at all. (more info via the links below)
Up until now the dev mostly focused on the technical aspects and it wasn't until recently it was decided to start spreading the word and promoting the coin. This means that right now the community is on the smaller side and the value is cheap. You don't even have to invest, you can just mine it if you want. Feel free to ask any questions on the forums linked below.
