I was wondering if it is possible or even likely that ASIC power consumptions < 1 W/GH will not matter in the future (years to come).

Calculating with the following constants:
- 25 BTC block reward (assuming that after the next halving the fees will make up for the reward loss)
- 25 dollar cents / KWh

Currently, with a 1 W/GH ASIC you pay ~0,5% of your income for power (350TH/s network rate, 100 USD/BTC)

Fast forward until the network hashrate is 3.5PH/s and lets say BTC still trades at 100 USD - the power cost will now be 5% of your income.

Does that mean it needs a network of 35 PH/s and a BTC price of 100 USD in order so you have to pay half of your mining reward for power cost?

Am I missing something (propably I am) or is it possible that - in case of bitcoin price rising - everything that matters for consumers in the future will be $/GH?
