I haven't made more research to find how many masternodes devs are owning... But with 1M coin, you can flood the network with rabbits (masternodes)
Another point. Devs wealth is at least 1M. Assuming miners are paid 4 coins per block (120sec), it would take 250k blocks to be on par with devs (if they stop their masternodes). It would take a litlle less than a full year to reach 1M coin for miners.
