You nailed it dude I know what you feel because I've been there also. I remembered the times when others don't believe in me and see three different facial expressions often every time I talk about cryptocurrency before: laughing, doubtful and uninterested. Even though everything change in a sense that they now believe in crypto's potential of making big money, I remain confused because no one still shows eagerness to learn about it despite of this fact (they don't even approach me at least). Now, I realized that even how hard you advertise and encourage someone to engage with crypto it will be just a waste of time and effort if he/she is not interested from the very beginning.
You have a point but don't be afraid. As long as you teach them properly and guide them for every decisions they made then it's not your problem anymore if they still lost — that happens due to their carelessness.
