Thanks for the breakdown. Though, your values are highly dependent on the price of BTC and ESS... $14.6 a year is actually huge compared to BTC mining right now - figuring a negative ROI
Obviously, it would be for holding the rewards for better days.
"supernodes is that they'll be available for presale ICO buyers" - is this true? I'm not an ICO buyer...
Well, I did not calculated costs of running ESS masternode server, either.
As for supernodes been reserved for presale buyers, yes, that was last info, if
they don't change it later
Edit:
judging by AMA info from here:
https://medium.com/essentia_one/essentia-technical-ama-recap-cdba11c0124f
they're considering if its the best idea to keep it for presale buyers only
