Sorry but Masternode model project and long term are not really compatible, it have to go fast, more with premine (sell off devs), cause :
No limited number of MN result fight with stupids holder sell off for ROI, without thinking long term view = price down , down down > no profit > no interest > trash

then you have to active PoS at same block of MN

and yes you have to clarify who you are (the team) , to prove its not single man project
how much MN you will hold
how much MN you will sell and why (from my view , with premine , you must not sell MN if legit, that why you need pos at same time )
how much lock coin and duration.

without that you start the bad way
