I just did a quick test on coinedup to see what was going on. The buy price was at 0.00006689 with a few sell prices between 0.00007 and 0.0009. With 0.25BTC i slowly upped the sell price to 0.000095 and a few small buy prices around 0.000075, but while doing so someone dumped 2000 @ 0.00006689 again.
Clearly some big miner is manipulating the price very low, probably to scare other miners while keeping the difficulty low.
My advice is to mine the coin only if you can afford to keep it longer, and buy low when you can. Be prepared for very low prices while that miner is doing his manipulating.
