As a parent, of course I want the best for my child's future. But we need to realize and understand that there are phases in the development of our children. teaching financial management, Bitcoin and Crypto to our children is a great thing if it is taught at the right time or phase. and certainly not by coercion or pressure.
There is time for everything simply. If you teach your child or anyone in general something at a wrong time, you have wasted your time and efforts, and they most likely will not learn it because they are not interested as interest contributes greatly to learning. Understanding the right time to teach someone something is also important and a good skill to have as an educator or teacher, it is what will distinguish you from other educators or teachers. As a parent, you must know this as well if you intend to teach your child about bitcoins, so it does not look like they don't want to learn about it and then you choose to stop and never mention it again.
Also for me, there is fixed certain age at which I would say that my child is now ready to start learning about bitcoins. Some children develop faster then others, and other slowly. As a parent you should be observant to know.
IMO, at age 10, they can be introduced to Bitcoin.
It may be Age 10 for some kids, for others it may be earlier, others later than Age 10. It is unique to every child.
