IEO is the right decision and the exchange is quite popular. I'll buy some tokens for me to just sell more in the future)
I like the projects that conduct IEO. It gives more guarantees for investors. Usually exchanges check the projects.
Cryptocurrency develops and become better. After ICO comes IEO. It is a new way of development of public sale to guarantee more rights to investors.
It was a lot of scams of ICO and investors stop to trust ICO and invest money in them. That is why appears IEO.
