Yes I have been watching that large buyer on and off for a few days. I don't know how genuine he/she was.
I thought that maybe it was there to prop up a slowly diminishing share price.
I for one sold half my holdings last week @ 12c then yesterday the rest @11c.
This one might drift down further yet, then suddenly explode to the stratosphere.
I'm watching closely from the sidelines and will jump back in if need be.
