This is true, some projects which failed to raise funds during ICO now turned to exchanges to run IEO since that's the new craze in crypto space. But IEO is better than ICO since there is surety of listing and investors believe team is verified by exchange.
I agree with you . IEO brings a new experience to all investors and it reduces a lot of risks when investing in new projects. In my opinion, the presence of the IEO has caused many scammers to feel miserable because they can not make money this year and i am sure the IEO will be a new trend that people should consider investing in a this time because the profit it brings to investors is very big . Maybe many people will think differently from me but on the positive side, IEO is much better than ICO
