I think the reward system could work. Devs have clearly decided this isn’t mining for profit, but mining just enough to secure the network and earn enough to pay for your own transactions. I think, too, that there are other possibilities for the network down the line that may make us all think differently about mining for rewards, ie, if the ideas that will run on top of Lynx are good enough, there may be plenty of people willing to support the network for free, just to enjoy the benefits of greater returns in Lynx. Just a thought.
