From the first day you tell one person that this is the place where you get your money from he will start asking you to help him and you don’t have a choice than to help him because if you refuse he will be the first person to become your enemy and some friends are not good people immediately after you show him he will go and spread the news everywhere and gradually many people will start pressuring you that they want you to show them way to make money and from their many of them are your enemies that want to see your downfall will have the opportunity to hurt you, so remember that is not everyone that is smiling with you are happy with you.
This only happens when you've got very hungry friends around you, your level of giving others a glimpse of your success should be a measure of their being on same or higher standards so they can process those information without feeling defeated. That's why you see that big men hardly make friends with poor men because they're not on the same page and thinking rhythm.
I have a friend who never discuses in details his business activities and financial life with our group of friends until he's alone with me, reason being that he's afraid of victimization, exploitation and envy. He even feels free to tell me about his future plans and I share mine too so we encourage each other.
Before you tell someone how you make your money, please ensure the person makes enough money too so it can be a friendly discussion and a motivation for another side hustle in crypto for the person, else, just keep encouraging the person to work hard and earn a living.
