Eternity Coin is a sub $100 masternode (for the moment) with a 30-40% return per month.  From an investment, this is a good buy and I have checked out their community on slack which is very active and enthusiastic.  Overall it's a good investment for a masternode for people wanting to get into it.

EternityCoin and ArcticCoin are still low entry points, you're looking at a masternode for the $100 range, not sure anywhere else you'll find that now.  Compare them to ChainCoin and then look at ChainCoin's growth and how expensive it is to own a masternode there now.  EternityCoin still has a really good ROI with EternityCoin having a 35-40% profitability per month for owning a node.  If the price keeps rising, that's well over what you invested. Rare to find sleepers like this even at these price points.  Might pass on ArcticCoin because my Russian is a little rusty.  Looking for more so post them if you know of any great investment opportunities like these.

Another coin in the list sud posted that hasn't made it into these main lists is Eternity Coin (ENT).  I remember a few weeks ago ChainCoin was even cheaper than Eternity Coin is right now before it went mainstream. Right now you can get a masternode for 1000 ENT which is about $50-70 with a payout of 7-10 ENT a day.  Looks to have a really good ROI.  Any other sleepers like Eternity Coin?  

Any update on these coins? Looking for a good masternode coin that is still cheap, similarly to ChainCoin a few weeks ago.  I'm looking at Eternity Coin (ETN) becuase it's about $30-$45 to own 1 masternode that produces 7-10 ETN a day.  That's a pretty good ROI.  Any other coins like this?

EternityCoin looks to have a great ROI and is currently one of the least inexpensive to get started on owning a masternode.  What other coins are there that would still be a couple hundred or less to own a masternode?  I remember ChainCoin being $0.34 and thinking I should pull the trigger to own a masternode now it's fluctuating at $4-$6.  Looking to get in before the crowd.  Any suggestions? 

Eternity Coin (ENT) only takes 1000 ENT for a masternode.  Right now that's $30 per masternode.  It says it earns about 7-10 ETN a day which is a great ROI.  Here is their official website: http://ent.eternity-group.org/
