IEO in Dcoin exchange? I think this is not popular exchange so if you want good investor people then you need follow other exchange like top in cmc. I was reading roadmap of your project and good think I'm impressed but we can expect other exchange.
I think the idea is to start from a smaller exchange first then grow thereof to a bigger one. Also, you should know that one of the driving force or deciding factor of a successful IEO is the idea, the product as well as services within that project. So let the team continue working while looking for major exchanges.
