Recommendations of any investment assets are always risky, especially when dealing with family members. This risk is amplified with cryptocurrencies, considering that the majority of people don't understand that you can easily lose 80% of the value within a single bear market. And guess who gets the blame?
Indeed recommending someone into Bitcoin is risky but however I think it will be more better to recommend family
members than outsider reason because family members knows you very well on what you can do or what you cannot do because if for instance you introduced an outsider to invest on Bitcoin and eventually he decided to use his investment for trading and based on how volatile the market is he lost all his investment there is a chance that he may come after you thinking that you lured him into something that would consume all his money.
But however in terms of family member no matter how the investment turn out they will only feel bad but they can never come against you because they know the person is not capable of luring them into something that's not real, so family is more advisable in terms of recommendation but however the person should be able to educate them concerning the risk involves while investing because I realized that one of the reasons why most people get into trouble with the people they recommend was actually lack of orientation they never informed them on the possible risk associated on the investment.
