IEO and ICO is very similar. Same thing you are buying but in IEO there is a little bit upgrade. So of course upgraded one would be better.
Maybe ICO will dead on next years..because many clproject use IEO program and many investor going to choose IEO for their investment? and ICO will be dead nothing investor?
Really? how did you say that ICO by next year will be dead? Since both are giving most profit to anyone. IEO became trend only because they are supported and backup by the exchange platform. But it doesn't mean, ico in the near future will become useless, I think not. Though, its an advantage to to have an exchange already even the project is still running in progress.
