As people, the only thing we can do is to remind them and not force them to do what we want, of course it's not like that and it's not good either. Now, it's up to your friend to trust or believe what you say, because that's the way we have friends who don't understand everything we say right away, they can understand but for sure it's later.
Giving advice to friends who need it is not wrong, it is true that accepting or not receiving advice depends on each individual's rights. Therefore, when giving advice, we should do it well and explain it easily so that our friends can easily understand it to make their own decisions.
I agree giving advice is different from pushing your ideals to the person. So in giving advice we should observe and do things in moderation. Just give him the needed information about Bitcoin and give an example of why it is necessary. We don't need to push hard and convince them since they have their own mind to balance things out and think for the solution for their problem after getting the necessary information.
In addition, it is also important to understand that every problem faced by someone can be different and therefore the advice we give may not always be suitable or relevant to their situation and thoughts, we must try to explain again. we also need to understand their situation well before giving advice. As friends who care, we must always be ready to listen and support our friends in explaining something, especially when it comes to investing. Sometimes, providing emotional support can be more helpful than giving unsolicited advice. The point is, don't leave your friends alone who don't understand investing.
Nope, the advice you must give must be related to the person's problem. If we are the ones giving advice, we should be carefully learning the situation so that we can give good advice to the person. If your talk about unrelated stuff to the person's problem then it is better to just keep quiet. Talking non-sense might be an insult to the person who is seeking advice since it means you are not giving or paying attention to him at all.
