what about mastenodes? airdrops?
at one point you should make less coins per block.
Masternodes are possible. Space was specifically left in code for potential addition of Masternodes.
As far as reduce block reward, can be discussed but as of right now it will stay as is. Would require fork anyway so maybe when/if add MN we can do so.
Basically we can leave this up to community to discuss and come up with ideas.
I think you should go for masternodes as quickly as possible. Coomunity will grow very fast. Everebody loves masternodes. Coin should attract more people. If you make good roadmap and target some date, it will be very cool.
