Many people have being blamed by friends on several occasions on why they introduced Bitcoin investment to them.
Depends on how you introduce Bitcoin to friends. If the goal is to introduce something that is good for investment, because people earn and get rich with it, then I would refuse introducing, even if I will be asked to teach. If a goal is to test how technology work (for example to show that working PC can not only consume electricity and enlarge bills, but also "produce money"), introduced alternative way to fiat payment, then I would consider introducing bitcoin to a friend.
My friends rarely ask me about Bitcoin. Only a few and indeed their interest is because of publications on social media for now. Their interest is of course, related to the benefits of investing in Bitcoin. Rarely will they focus on using Bitcoin as an alternative to fiat payments.
Their initial understanding is not wrong, but it is our job to provide more details regarding their interest in Bitcoin which could be risky for those who do not have the knowledge. If their interest is in investment, then we can provide information regarding good investments and how to plan them well.
My experience with Bitcoin if following. Friends who are not "old conservatives" does not even want to hear about Bitcoin or crypto. As if they are scared of something unknows and usually prefer to change topic of discussion quickly, when cryptocurrency appear in it. But I can suppose they want to change topic because they dont want to show that they are unaware totally of it. The rest somehow somewhere already heard and know what crypto is. Bitcoin price growth made crypto so popular, that there is no need even to introduce it to someone. The internet is full of description and detailed guides, that everyone can find and understand everything themselves.
