It seems manifestly clear that 2.4 GH/s on 1st Jan >> 8.68 GH/s in two weeks (tm). Heck, 1 GH/s on 1st Jan > 8.68 GH/s in two weeks.
Now, we could just wait for the last hardware to arrive. We would be hashing at 700 TH/s with 80,760 shares in a couple (?) of weeks. We could pay 65% dividend and all investors with a short term view, would be happy. Until they realize a few weeks/months later we are slowly dying and dividends dry out.
This is the truth. Unfortunately, it still appears to be the truth after IPO. The reason dividends were going up was due to initial deployment not because reinvestment could keep up with difficulty rise. Leaving the reinvestment rate alone means investors lose less, and you still make a healthy profit.
