It's better to never give any financial advices to people. They will always blame you in case of any losses and some of them will even not be grateful for advice in case of profit
I also think so, it's best not to give any financial advice to anyone because we don't get any benefit from them but we will be blamed if their investments lose money. So, don't waste your time doing things that don't bring you any benefit or profit.
I rarely give investment advice to anyone, including my relatives. I don't want our relationship to fall apart just because of money. If someone wants to invest and is serious about it, they can search and research online. In today's technological age, finding anything is not that difficult. If they can't even take the time to learn about investing, it's best not to invest.
