There is absolutely zero proof of Bradford being paid in stock. I would HIGHLY doubt that they would agree to such an arrangement since it would effectively destroy their independence. I'm assuming they were paid part of what they were promised and are awaiting further payment from BGMO. Good luck to them on that.
IMHO the dumping has probably been judgment creditors who have been paid in the newly issued stock which is restricted upon issuance but immediately convertible into free trading shares since they are being used to pay a valid debt. I'm guessing that there is a lot more of this stock out there but the sellers are giving it a rest before putting the pedal to the metal again, we will probably see multiple periods of mass dumping, followed by silence, followed by mass dumping. What Fun!!
