2) The total network hash rate will hit 1500 TH/s (1.5PH/s - peta hash) by that time.
3) Lab_Rat will only ever deliver equivalent of 100MH/s per share. (contrary to stated plan)
4) These shares will continue to be worth 0.15 BTCs each with no growth (or reduction).
The problem is right here. You can say that
BTC0.15 per 100MH/s is a great price right now (network at ~250TH/s), but when the network reaches 1500TH/s, 100MH/s is worth then 0.15*250/1500 =
BTC0.025, an
83% devaluation.
