I don't think so. IEOs are new style of advertising and promoting a certain project. First of all, this does not guarantee that the project is legit. Also, your thread title is being opposed by your explanation (you are more of explaining IEO as an unsafe way than as a safe way).
The title is: IEOs are more safe.
But there are still problems that must be solved.I didn't meant IEOS are safe. You are right. In this topic, I have focused more on disadvantages. I just meant that IEOs are safer than ICOs but there are still many challenges with cryptocurrencies fundraising. In my opinion creating IEOs was a good progress when we compare them with ICOs. Just this. There are many problem with them.
