there was a lesson I lean from here. when you are preaching to someone about Bitcoin, you shouldn't talk too much, and you shouldn't stay long and you should also allow them make some research and ask questions about what we are preaching to them, to avoid loss at the end.
I don't know, how you see it.
Trying to make someone buy Bitcoin or any investment is not a good idea. Why? Well, because these things can be pretty tricky. They can make you money, but they can also make you lose it just as fast. Everyone's got different money goals and how much risk they can handle. So, it's better to let people decide on their own when it comes to investing. Give them the facts, let them think it over, and support whatever choice they make without pushing them into it. That way, they can make the right decision for themselves.
Remember, it's their money and their future, so they should have the final say in how they want to handle it.
