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.
If everyone does not believe in ICO, you and ME cannot be here, I object if you call all ICO fraudulent, because I make a lot of profits from it, but for fraud problems it is due to carelessness and lack of analysis in researching ICO projects that will chosen.
