But why ICOs when it is clear they are no more in fashion or will I say dead, when was the last time a project did ICO? That shows it is no longer working but IEOs now are leading. In my opinion, IEO wil be better as investors will have a sense of funds security unlike in ICOs where the team can do whatever they like. Also, in addition to this, the exchange which will be used should be a good one might not necessarily be top exchanges (maybe for fear of fee, although they have their own benefits) but any reliable exchange would be okay, in this way you have tackled any form of fraud which investors might be weary of.
