Try Initial Exchange Offerings. I thought that security tokens offerings will be the revolutionary idea, but IEO seems to be much better.
IEO is more promising than the current ICO, but it seems the ICO opportunity to be repaired is still not completely closed, so in my opinion, even though EIO is currently more potential, the opportunity for ICO can be developed in the future is still there because of a gap that can become a hole.
We have already seen ICO's but most of them are stealing the people money without any developments and this makes many people already lost their hopes on the ICO's. Recently IEO is conducting by the exchange, but at least they will research the companies before listing the IEO.
