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.
What you say is not wrong, but there are many other factors can causing ICO to failed.
The most factor from my opinion is, many investors has been scammed with ICO's in the past.
So the investors will think 100x more if they want to participating in ICO, only choosing the trusted ICO.
