Do you plan masternodes?
No, the network is calculated, to function without masternodes, in fact staking interest, is sufficient.
Staking under PoS 3 is the best now,
I am not sure about Casper (staking under Casper may also be very very good).
PoS 3, ZKP, Ring Signs, TOR - Obs are handling everything, we dont need masternode.
Masternode need money and this may make the market to be centralized,
not a good idea to hunt coin with msnode, what is the point of msnode? It makes the msnode ifself may be identified, what is stealth if identifiable?
No need.
XSPEC is ways beyond current other coins, it may be the best.
