If you tell your friends and family about Bitcoin without giving them any sort of in-depth financial advice and they go ahead and invest, how do you deal with it when the market dips very low and they silently blame you for losing them money.
Explain them the risk of investment. Tell them that it is normal for them to somehow lose a small amount of money because they are just beginners and they lack knowledge about what bitcoins is. So, tell them not to blame anyone because they agreed on this. And bitcoin is part of investment so it is natural that it is risky anyway.
