Proof-of-stake is being brought to the ethereum network to make the system more efficient and thus it makes ethereum mining more profitable.... the need for expensive, power intensive mining equipment is eliminated, as the process of validating and authenticating transactions is much faster and easier...

This basically would increase the efficiency and so should increase the payout as well. This is just my analysis of it but I have faith in this company as they have also found a way in troubled situations !!
