Change is constant and the day the world stops changing, then something is terribly wrong, the ICO model has been found to have many flaws and criminals has taken advantage of this fact until people finally got tired and stopped investing in them. This leafy a gap in the fundraising aspect and now IEOs had come to fill that gap, I wonder what the next would be. I see a long and colourful future for IEOs before that happens though.
There are flaws inside ICOs, and IEOs. There is nothing perfect, so that is life, and soon we will see others replace IEOs to become better method to do crowfund raising. For now, when IEOs hot trend has still been here, and still been hot, why not enjoy its ride and choose good exchanges and good IEOs for your investment.
