I have never invested in any ICO. I saw that most of the token / coin after being list on exchange was depreciated by more than 50%. Are you disappointed or all of that is in your plan ?
The trend that you describe is inherent in projects in the last year and a half. Look at the projects that were released until February 2018. If the project had a real application or was innovative in its industry, it gave a minimum of x2
but after end of 2017 year and middle 2018 many project turn out scam, and even the ico are succesfull nothing any product released to investor and nothing any innovation from new project like they offered when ico campaign running
