Currently delivers 28% per year on the cost of the masternode.   You can compare that to other masternode coins.  Imo, once you get into the 100% per year range, the coin is probably doomed to its own inflation.

Masternodes are like lotto tickets.  You hope you can get on board with a coin going the way of DASH.  But that's not going to happen unless the coin's community does what DASH did.  So before you look at the masternode cost or ROI, you need to look at the overall health of the coin.  

Over a year and a half ago, DASH was pumped and dumped, a lot like CHC.   But CHCs future won't have DASH's current success unless it imitates much of it's process.   It's not even near it right now.  

It's possible. Right now, CHC's future is on a knifes edge as it attempts to land on it's feet after this terribly malicious pump.  

Personally, i would not invest in masternodes until they deliver more than just a marginal annual rate of return.   Any of these coins could either die, or lock your capital away for years, costing you lost opportunity in the meantime...unless the masternode comes with a functional voting mechanism that ties the community together in an organized fashion with the financial backing to get things done.  

With the right mechanisms in place, any of these coins could grow 10x in a year.   That's why the fundamentals of these coins is more important than the masternode, unless you treat them like lotto tickets.

Period.  

Anyone who tells you otherwise is a fraud.
