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?
It used to be good crowdfunding, but not anymore IEO has replaced ICO this is where investors are going right now, they do not want to lose their hard earned money and it is fast too they can trade it next day, compare to ICO where you have to wait for months to get your money back sometimes you lose.
