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.
If you just introduced bitcoin to them and gave no financial advice then it is their fault for investing in something they had no prior knowledge they may blame you but it was their fault, now if you gave financial advice telling them to invest and they listened to you they still have a great share of the blame since they invested without knowing what bitcoin was about but in that scenario you are at fault too by not explaining them the risks.
