In my opinion there are no high quality masternode project except Dash. However I think overall masternode project is bad. the passive income is just an illusion. I understand that people are very attractive to this, people are attractive with HIGH ROI things - which means the more people joined, the price will be increased more. But eventually, when the market is overvalued, people will leave and the project is dead.
I'm also with DASH too yet i have some coins parked for some passive income but as expected it wont really be that big even if you do put up big amounts it wont really be still ideal
for you to rely on when you do talk about passive income but overall this is my choice and most coins/masternodes are already facing on the floor which simply
means that they do have failed.
