ICOs do not exist in this market, there are so many scam projects in the past and it makes people lose faith in ICOs. Now we have IEO, and it's a good way to help new projects raise funds and keep investors safe when they want to invest in new projects.
I do not agree. Going straight to listings, without proper time-to-market or product, directly influence the growth of scam/bot exchanges. The basic idea of the model is very good: credibility, price stability, access to exchange's data userbase, crowd sale is hosted on the exchange...but this gave huge power to exchanges, without proper regulation/licensing.
I've supported projects to communicate the value (brand/marketing), and helped one of the 1st biggest ICOs in 2017 to raise funds...and more than 15 ICOs and IEOs, and 2 STOs till now...and must say that IEOs make me more problems than ICOs. Why: 1 - bot exchanges, 2 - fees are amazingly high to withdraw money plus they push you to go public with them and than to give you raised funds, 3 - projects are rashing to exchange without vision, product, users..which further led to the extreme numbers of projects listed so users do not know how to recognize a good one, worth investing...
What happened is that companies tend to choose 'the model which works' no matter is it the right one for their business. We can see that everywhere - exploitation of 'what works' until it becomes a scam.
It is sad that happened, but i do hope things will come to its place...will that be ICO/IEO or fundraise...there is substantial room for improvement in the cryptocurrency-based fundraising ecosystem.
