Because they are the answer on how to gain back the confidence of the investors in the crypto space.
With the advent of IEO, investors feel safer with investing, although the number of projects that has come into existence is now limited but we can ensure that majority of them are good projects. I believe we quality projects more than quantity alone.
I agree with your opinion that if there is no IEO maybe there will be no more people who dare to make a new project because there are too many frauds that occur in the ICO.
with the existence of an IEO automatically can increase the confidence of investors to invest in it.
