On my side of things I want to teach my friends everything that I know in the crypto industry especially on Bitcoin but when it comes to the question with regards to buying or selling I ultimately avoid answering it and explain to them that this kind of decisions are supposed to be made by you. Why do I avoid it? Because I don't want my friend to blame me when it comes to him losing money because he followed what I said even if he/she doesn't blame me I will feel guilty that he/she had suffered a loss because of me. That is what I am trying to avoid I still say Do Your Own Research (DYOR) even on my friends because of it. Also I think this is better because in the long run they can be independent when it comes to trading cryptocurrencies.
