ICOs are toxic to the cryptocurrency world. If you look at the number of cryptocurrencies in the top 10 that aren't ICOs and are projects that haven't been premined with real use cases and have a community then the list is quite small. From the top, Bitcoin, Monero, DigixDAO, DOGE(kind of). There are other projects that are growing and have much smaller marketcaps, but for the most part a lot of projects are just not genuine. The sad part is these projects attract developers with good intentions and people that join community who are interested in the tech, but the project is a ponzi. All I can say is do your due diligence and read guys.
