As everyone knows ICO's are good for startups seeking to raise investment for their products. Nowadays IEO slowly gain popularity. Still i am confused which one is effective enough.
Also is it necessary to use Blockchain technology for raising ICO investment?
From my opinion, IEO is not efficient because you will need more money to holding IEO on popular exchange.
In ICO, you only need to hold a campaign to create some awareness about your ICO.
but IEO is more effective than ICO, because they are targeting audiences on popular exchange.
