I’m convincing them by explaining what they can get from bitcoin and what it is. And also sharing them what I gain from bitcoin. And I think inspiring them by talking about what other people gain and earned. But also while explaining them don’t leave them thinking only that they will only gain without any risk. Open their mind what danger can they can get from it.  Especially when it comes to their money because they should know that there a risk of losing their money so that they can’t blame you at the end.
