Most times people refuse to render help to others because of past experiences. When you are treated wrongly by people you trust, trusting people becomes a problem. This victim will never give a loan to anybody again because of this ugly experience. Lending money is risky which is why it is important to seek collateral before the funds are issued. If you think you are close to the person that asking for collateral might be improper, then let there be a witness or guarantor. To limit such ugly occurrences, give out only what you can afford to lose.
My cousin is very broken mentally and can't share this with any of his family. He can't take any legal action because Bitcoin is not legal. My cousin keeps saying one thing my best friend cheated on me then I told her a lot that what happened happened don't worry about it anymore.
OP since Bitcoin is illegal in your country don't you think it is risky to keep using it? I know in some countries using Bitcoin is a serious offence that can lead to fines and even imprisonment. Now your friend will lose that money because he can't seek legal action. It will be better to obey the law than to become a victim of the law.
