1. Peta promised 700Th/s back in january. four months later: 500Th/s
You're wrong there, they promised 8.68 GH/S / share and they almost delivered by buying back and "destroying" those shares (units outstanding went from 80,673 to 66,206 which represent a rise from 6 GH to 7.55 GH per unit)
Though, they promised 8.68 GH/s per share so it's still a 13% shortfall
The problem is that they are re-creating and IPOing those shares with new promises without waiting the market to stabilize. That's why many feels trapped.
I have the feeling that a week or two of the mine @500 Th and divs distributed amongst the 66206 units would have make things easier to understand.
