It's better telling people about the in and out of Bitcoin it's then they can decide to invest or not because they have already know what Bitcoin is all about so that what ever happened they won't put it on you who introduced them into the investment. If you only tell them Bitcoin will make them rich without telling them that Bitcoin can also make them lose money you are already passing a negative and a misleading information to them, they should know that Bitcoin doesn't guarantee profit not a get rich quick scheme as you will need to invest for a long time and with money you can afford to lose.
You are absolutely right. Many mistakes made by Bitcoin investors, especially newbies, are caused by those who introduced Bitcoin to them. They were not told about Bitcoin in detail, and this can be misleading. But if they are told about the pros and cons of Bitcoin investment, that will help them make informed decisions, as they will understand that they are responsible for whatever actions they take regarding their Bitcoin investment because a good teacher wants their students to grow, not by hyping Bitcoin, but by helping them invest with proper understanding.
