Sharing secrets and giving advice to others is completely different. I also tell a few close friends about my investments because we care about each other and can help each other out when someone is in trouble. But to give them investment advice in bitcoin, I never did. I think anything related to money has the potential to lead to an emotional breakdown, so I avoid that altogether. While I believe bitcoin is good for me, it will also be good for them. I just hope that one day they see what I have achieved, they will change their mind about bitcoin and go for it on their own.
Only those closest to you should know about your investments, maybe even only your wife / husband, or the closest person, brother or sister, if you have a good relationship. But everything that concerns friends and acquaintances, this should remain a secret, money loves silence.
As for financial advice, I'm of the same position, you shouldn't give anyone any advice, because if they fail, they will blame you. Even if it seems to you that this is very good advice that will surely bring money, refrain from advice. There is no exact algorithm that can enrich everyone, someone will use it correctly and earn money, and someone will understand it in his own way and lose everything.
