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.
Yeah, you are right. Learn from your mistake, lots of people today didnt think what they will do they just go with the flow at the end, they regret on what they do, just dont regret yourself, think in a good way.
