The most important thing when recommending bitcoin is to say that bitcoin is a very risky investment, if we have made them understand about the risks then we will not have a burden when after they buy and the price drops so that they lose, most people just say that bitcoin is very profitable so no care about risk.
Explaining in detail the benefits and risks that can be obtained in investing in bitcoin is the first step we must take when we invite others to invest, besides that at least we can say that bitcoin or crypto are assets that have a fairly high risk, so when he is ready to invest of course he is also prepared with all the risks that might occur, and most importantly never force others to follow us to invest in bitcoin because we will be blamed if he gets a loss later.
