Is this the wrong advice? A friend of mine took over his father's company because he is so old already and he told me about the money thats available doing nothing in the bank.
I told him to think about investing that money if he wants to keep the company growing, I told him about how MicroStrategy is doing so well using Bitcoin as a strong backbone of the company, I believe that even a small company can turn big if they use Bitcoin as their main investment.
You could have suggested your friend to study the Bitcoin market but not directly told him to invest in it. This way, your friend cannot blame you if ever his Bitcoin investment goes southward since we all know that Bitcoin cycle often goes up and down.
I believe your friend should realize how good Bitcoin investment is according to his own research (though you can give resources about Bitcoin market information for him to easily gather the information needed).
Or am I wrong? I need to know if this advice is a good one or a bad one, I gave him this advice because we are very close and also because I will do the same thing if I am in his shoe, this is the best thing i can think of right now.
As a Bitcoin believer I don't think your advice is wrong but to be on the safer side and avoid the blame, you could have suggested your friend to study the Bitcoin market and not directly tell him to invest his father's company fund into Bitcoin.
Our job is to give them advice so they don't make mistakes when investing, but all decisions are in their hands and the way they think about how to proceed with this advice is more relevant to their way of thinking. The context that OP is talking about is regarding switching companies and that is not an easy matter for him to do because if he makes the wrong decision his father's company could go bankrupt and giving investment advice is not a way if he doesn't understand.
No, I think it is not our job to advise people since we don't run a company that deals with such a matter. We can only give suggestions because there might be instances that we might fell short of knowledge and things won't go as we advised so it is much better to be on the safer side and take on a lighter position by suggesting not advising people on what to do.
