1, reject directly. You can say "no" firmly and explain your reasons, such as you don't understand futures, don't want to take risks, or don't want to break the law. There is no need to feel guilty or apologize for your decision, because it is your right and freedom.

2. Change the subject. You can interrupt the other person's request with some irrelevant topics, such as greeting the other person's recent situation, sharing some interesting things, or making some other suggestions. This can avoid direct conflict and show that you are not interested in futures.
