i am sorry to say this but it is the person's fault for losing money and there is nothing others can do for him. the warnings are there and we have been telling you not to trust ICOs since they are scams but you chose not to listen and give in to your greed.
you gambled and you lost. now learn from that mistake and move on trying not to repeat it again.
the worst is he trusted a fake admin of the project i wonder how people fall for these type of scam its really easy to tell. i wouldn't say Ico's are scam but he gave his investments to the wrong person. he'll definitely fall for other scam he cant even tell an easy one.
