Those that bought at 85 cents most likely are waiting for at least two bucks. If they did sell, it would quickly drive the price back down to 85, or lower.
To make money on a P&D, it is necessary to be quick. Keep an eye on the sell volume and jump to try to beat the dump. Keep an eye on the buy volume, and either buy or hold, as your nerve and guess power dictates.
As a long term investment, CDEX stinks. There is clearly never going to be a Valimed in every household in the US of A.
Certainly not in every drugstore. Drugstores buy in bulk, and count out pills or measure out the liquid according to the prescription. They do not "compound' anything.
How many hospitals or drug manufacturers will buy them a valimed? I dunno, but I very much doubt that there will be many that do.
