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.
