Investment is always a risk especially if you are talking about crypto. It was said and written hunderds of times that one should not invest more than  he/she can afford to loose.
Crypto and ICOs are high risk investment because once you put money into it it is hard to control or affect what will happen than. You have to rely on the project team or the industry trend. But in most of the cases you can do nothing but stare at what is happening to your balance.
