For me, i don't support the ideology that ICOs are killing Bitcoin. Remember, through ICOs most people has got to know about cryptocurrency. Through the awareness creation made by ICOs, the entire crypto space has gone global. ICOs added a new sense of value to the crypto market.
No, the ICO's are part of the Creative Destruction in the crypto space. Innovations will come forth and test of time will determine if they will survive.
So far, the only survivor after 10 years is Bitcoin. Let's see if other coins and projects will still be around after 10 years.
The they is about the product. When they can create such a useful product and then it will be so easy for this project to survive and follow bitcoin in the future. Bitcoin is not a security and then the ico must no become a security to still exist in the cryptocurrency. They need to create a utility token or coin.
