There are many ICOs out there, but more than 50% of them fail.
From my analogy, could this be the reasons why ICOs fail?
1. Being too complicated:
If you want investors to favour your ICO, make sure they understand your coin offering. Be concise yet interesting, creative yet not too techy and try to explain concepts from scratch. Of course, the detail you go into is likely to depend on your target audience.
2. No unique Use case and lack of creativity:
The reality is, ICOs are not straightforward and with new ideas and concepts arising daily, you need to get noticed and that means coming up with some unique Use case
So, before a developer even attempts to launch an ICO or enter the crypto world, ask yourself: "What will make investors choose this particular ICO over a competitors ICO?"
I believe the list continues.
I think its more than 50% and even go until 70% failure. Because people are scared on investing in ICOs due to heavy scams in this field. Nobody can verify whether the project is real or not. Severe scrutiny is needed in order to make ICOs beneficial not only for projects but also to the investors.
