Thank you for your advice, but I think it is not good time to take part in ICOs, most of the ICOs have not enough value, but so much risky.
Being risky does not mean you cannot take part in it, what is important is for you to know how to minimize the risk to your advantage. We may say because of the risk, we want to stay away, but at the same time, staying away will also make you miss the best part of it. The advantage of ICO is to be a part of a great project from the start and early adopters always end up having the best in any case. Once you can do your diligence with proper scrutiny, then you should be fine.
