Do you have better advice? Genuinely? For my friend.
If you hold a coin for a long time and invest a large amount there and lose it, then it is really painful. And if you decide to harm others emotionally from there, it will be a wrong decision and it comes from emotions. In this situation, your friend needs to refresh his mind and for this he needs to visit a place surrounded by natural beauty so that he can refresh his mind. After that, he should focus on his work again and start everything anew. People make decisions emotionally, which are never good, although they cannot feel it at that time. So as a friend, you should stand by him, comfort him about the issues and if necessary, go on a tour with him, so that he will return to normal.
