Masternode = Proof of Stake mixing node only for the wealthy requires 1000DRK and imposes 20% tax on Miners
Miners = Doing the actual work to secure the network.
The mixing nodes require far less resources, and are basically nothing more than a wallet with some additional code activated; this is giving far too much reward value to the early adopters and wealthy. This is bad for the coin.
Mining is the democratic process that will determine the future of this coin; I'm not mining on a pool that pays masternodes. Enforcement will cause a hard fork with the miners abandoning the enforcing branch.
Fix the masternode so everyone holding the coins participates, regardless of wallet balance and make it truly peer to peer proof of stake/proof of work hybrid. Make everyone a Masternode, not just the wealthy/early adopters.
This will create many men in the middle, most of them working for governments.
