True that deals fall through for MDMN -- but from my limited DD it appears those past deals never made it even remotely as far as this one that is supposedly a "done deal" already and merely just lacks public disclosure of name. It's passed the promise stage and onto the they "either have a deal or they lied" stage.
If it is a scam, it seems to me that the gig is pretty much almost up and odd that there isn't more selling pressure if so. It certainly isn't trading like a scam.
What it could be is that $90 million on say 900 million shares outstanding eventually (for simplicity) = .10/share cash plus 15% interest of some completely unknown wild card, hence it trades .15 to .16 -- the book value plus .05 to .06 for the 15% interest. The trading actually kind of makes sense vs. the supposed value. I'm hoping this is legit and the big name explodes the price then I'll take my huge profits and run. If it's a scam then it risks halt and/or going to zero very fast. We shall see one way or the other shortly I suspect.
