One thing IEO fails to tell people is that it is very difficult to participate in it, you have to be on queue for too long and hoping to participate which you might not get a chance to do so before the token gets sold out, which majority are being bought internally. If IEO can solve this challenge, then it will become perfect.
Exactly. I will say though that maybe on IEO it's "cheaper" because everyone has the chance to buy it, without the ICO "bonuses" to dilute the value or without those nonsense bounties that give away 5% of the value. At least everything on IEO is as is, at least with the ones I've seen. Other than the tokens allocated to founders and what not, every other token is sold on exchanges with an IEO.
