Most ICO projects in 2018 become scam, basically they do not have real projects and seek funding through the ICO. So be careful before investing in ICO.
Not all of it. But hate to say, that scam ICOs are more than the legit ones. But in the start of 2019, I can see many new projects with potential. Also, the era of IEO began to start. Most project now are using this method of raising funds and to gain trust of the public. Why? Since exchange already filtered some ICOs and already they address the problem of identifying a scam or legit one.
