IEO is much better than ICO, if we look ICO even have a hardcap but they dont have listing date or delaying for month and may be year,, at that points IEO so much better than ICO especially IEO from binance
I think not all IEO can end well, a few days ago it happened in a large exchange place like Bitrex which held an IEO program for its members but after that the price of tokens offered became very cheap and made a lot of losses for the participants.
This new IEO thing doesn't give out guaranteed profits yet investments would be most likely a gamble.The good thing here on IEO compared to ICO is that
the tokens is already listed on certain exchange unlike on ICO which after they finished they do still seek out for exchange listing.
IEO is prone to manipulation or dump so if you do able to get in on the IEO sale then better secure it out once its been traded and don't wait for the dump.
