Hi brother I am single and still I ma not married. But in future I plan to do marriage. And if I have had choices than I will Keep my portfolio for my children and also will tell them if they have any kind if Interest in this field. So that's a good thing Bitcoin should be a good investment for us. That's why I like Bitcoin so much.
You must really introduce bitcoin to your child as an alternative investment and the best hedge against the evils of fiat currency, you must teach your child about how bitcoin was created and for what after your child is old enough to know about bitcoin according to You. If today you really like bitcoin and benefit from bitcoin, of course you won't close yourself off and enjoy it alone, in my opinion, don't just talk about interest but teaching bitcoin is a sure step for your child's financial freedom in the future and maybe you need to start as early as possible.
