Your project has an interesting level structure but I don't clearly get this part:
Each masternode will only work at its own level and the following next level.For example if person A starts their masternode today,their masternode will work without adding any extra collateral coins until May 25,2019.
These steps are all automatic by the chain.
Does it means your collateral will automatically be greater, i.e. you gains some coins? You say the following level, in your exemple the following level is Second Level, Nov 2018. Can you please explain it better?
