Many, many, many months ago I wrote just about the same things you did. I'm not going to look it up, and my memory is very foggy about what exactly I posted. I think I wrote that by the time silver got to $43, ECU's share price would then be zero.
Needless to say, I was being very sarcastic because as usual, silver was rising and ECU was declining. I extrapolated the silver price using ECU's decline to figure out where silver would be when ECU did its grinding decline to zero.
Seems some things never change.
