Thank you for bringing this on board. Well, parenting is a large responsibility that no one knows it all, nevertheless, we should be wise about it so that we do not deny our children some benefits and expose them to what they should not know. Like I always say, if it's about adult and risky things, it is bad to involve one's children until they are adult enough to be able to handle it. But one can educate them about them and not engage them in it. These are two different things, and the purpose is for the circumstance they probably know it behind your back, letting them know will make it not a big deal to them.
Specifically about the subject matter, it is good to let your children know of the positive things you do. I am a victim of this as my father was a successful businessman but he never allowed any of his children near his business. His line of work is now going extinct in the family since none of us is interested anymore as we are engaged in different aspects of life for earning and living. Had it been he did otherwise, that successful business would not be dying, but it is too late now. We are not even in the state he resides anymore.
As good as letting your children know about what you do that fetches you money, you should be careful about it as well. Exposing children to earning means could make them not to be serious with their education which is the primary goal at the time. If you are such that can help them take their minds off it, fine, especially cryptocurrency investment that is easily accessible, it will be good for you. Above all, it should reach a certain age before you expose your children to such things and also know the kind of children you are exposing to such to avoid regretting it later.
In my own opinion I feel like, nothing should be enforced on a child, he should learn to grow to make his own choices. The main responsibility of a parent is to show guidance to his/her ward. There are certain ways those who run family businesses do their work, the child who is going to take over the family business will be handling affairs of the company when his of age, seeing how the business is being run, his father or successor who in no doubt knows he will be the future of the company wouldn’t want to hide the business from his child. Instead he will bring him close to train him to be a better leader, before mounting the mandate on him, he should have seen the blueprint and log books of the company if he’s to make a good leader. Also before the father will hand off his business to his child, he must have access the child to know if he/she is worthy to take up the mandate. Not every child will want to go in line with their father business, some children are driven by different ambitions, you can’t force on responsibility in someone, you will end up not getting what best for that person.
It is good to groom the kids at thier tender age, know their worth and place, if the child doesn’t want to be part of the families business fine, he can go venture into other business, support them regardless of the choices they make. Also I do not agree with what you said about children not taking their studies seriously when expose to earning. They say charity begins at home, you will know a good kid from his home training. If a kid decides to live waywardly that means there must have been a leak from the home. Something is not right in the home either the parent has less time for the wards or even show them no discipline. They are good children who will stay focus in school just to make sure they keep up with their family legacy. The idea of money changing a person doesn’t just sound well with me, if you are a good person you are a good person.
