When I fix someone's computer, they blame me when something doesn't work afterwards. I expect a similar result when I recommend Bitcoin: if it fails to produce the expected result, they'll blame me. So I just don't give any investment advice. Not for Bitcoin, not for anything else.
One more reason not to recommend Bitcoin is that I don't need people to know I'm into Bitcoin.
Lol, this is also why I have stopped suggesting or recommending things to people in real life, because I have some harsh experiences in my life where I used to either help people get some stuff done, buy something for them, recommend or suggest them something that they could buy or get into, and then later, if anything had gone wrong with that thing, I used to be the one to take the blame for it because I was involved in the process. I was like, what the hell?
What's even worse is that even if they approach you first because they feel you know more about a certain thing than they do, and if you then suggest something and it doesn't meet their expectations, they will still blame you for it.
That's why I decided never to suggest or recommend anything to anyone and always stay neutral and ask them to check on their own. Even with cryptocurrencies, if people ask me, I tell them to please learn and then decide. I never suggest anything.
