A person can't persuade another to do something when they have not yet seen the results for example, you as a child you depend on your parents for every of your up keep and at the end of the day you go telling them that you have an investment you want to introduce to them, and knowing how our African parents can be smart with questions especially when it comes to an online business that involves money it will be a waste of energy trying to persuade them when they haven't seen the good news in you but when u stop depending on them and pay ur bills they will be wondering what's going on they will want to know what you do from there u fit run enter them and they will be eager to listen.
It won’t be a complete waste of time, in my opinion. How your parents will react to the information will depend on the type of relationship and connection you keep with them. If you are the type that respects your opinion, even when they are still the ones supporting you with little things, they will still listen to you if you bring investment discussion to them as long as you have every detail information about it and you can answer all their curiosity questions, but if they still don't want to go ahead, you let them be; that’s their decision, not because you haven’t invested in it but because they don’t want to take the risk.
I can remember finding myself in a little bit of a similar situation during the time of MBA FOREX Investment that was before my time in this forum, where I convinced my mom to support me with money that would be collaborated together and invested with the expectation of weekly payment, but at the end of the day the money ends up being stocked there. She trusted my information not because I have first-hand experience but because she trusted me as a person and her child.
