I think IEO is good and more reliable than ICO. In IEO there will be fewer scams. But I dont like that in IEO only exchanges and investors and start-ups can earn, and theres no place for bounty hunters.
Like how the ICO's growth is relay on the private investors. This IEO are really need to be listed on big exchanges. If the coin has listed on fake and small exchanges means we will not get the reach or anything for that.
So be closely look at the IEO where it is listed. Even that coin listed on exchanges then it will dropped bigger in few seconds for huge volume of sellings.
