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.
Because most of them are not launched for getting succeeded. They are designed to fail! They are designed to make a handsome amount(or whatever they may get) of money and run away! They were already destined to this!
