First of all I have seen so many post similar to this topic so I like adding my own ideas when I come up with a plan so I will share a little of my own knowledge here.
So many people in this forum have been asking what they would do if they persuade someone to invest in Bitcoin and crypto currencies and at last they don't see success, so I came up with my own idea so I won't go wide I will just state based on the topic I have made.
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.
So the only way to persuade a person to something is when u are the example of ur words.
We all knows that cryptocurrencies is not stable because they all fluctuate, even the coins we think is stable is not stable because it can not stay in one position for over a year or a half. Even though we have made a profit from crypto currency and we advised someone to invest on them, those same people you advised to invest in Bitcoin might not be opportuned to make a profit as you do, they might lose and you will answer to their questions. Crypto currency is not for all that is the reason why you it is not good to persuade anyone to invest on it.
