how is the sale different from ipo? even after the sale you are still left with 95% of the coins. that's a bit of worry.
that's the point ,no one can promise dev will not sell NHZ in any time, do not forget ,dev have more than 99% NHZ.
so i think NHZ is very danger as to investors , it not like NXT or NAS , the dev of NXT and NAS ,they just keep a little of coin ,but NHZ keeps almost all..
