Yeah. The more Dash's value increases, the more difficult it will be for anyone to enter in the masternodes area. It is becoming more expensive to set up your own masternode, and I believe that if no change is made on the protocol level to reduce the minimum amount of Dash for a masternode, then the cryptocurrency will become more centralized. They should make a dynamic Dash fee required for masternodes to keep up with the USD price, instead of relying on a fixed amount.
Interested users could create some sort of masternode shares. Ganging up as a dozen, buy N~M masternodes and share the revenue according to investor's shares. I can foresee that coming.
(I have not foreseen cloudmining)
But how to engage the risks of a single entity in control of the group owned node running away with all funds?
