The market cap, the .0002 share price and the daily dollar volume of ERHC are all a joke to real investors. These type of numbers are indicative of a company in deep financial difficulty that may not survive.
But these types of companies are much loved by day traders because they know any rumor, no matter how absurd it is, could result in huge percentage gains. So they can get in and get out fast and perhaps bank a profit. It's fairly obvious that is what happened here the last few days. Whether there is any truth to this latest PR is irrelevant.
The volume the day before the announcement and the subsequent dumping the day of the announcement indicates to me the objective of invoking the bitcoin bubble to make a quick profit worked exactly as planned. Someone walked with a nice profit and now they're long gone.
