Even though Bitcoin does not limit a person's age in owning Bitcoin, I personally will never involve children at an early age for Bitcoin things even though it is not written in the rules of owning Bitcoin itself. But if we see that there are children who understand Bitcoin and understand how to store it and how to exchange it on the exchange, there is nothing wrong with letting him get involved in cryptocurrency and Bitcoin even though he is still very young.
If there are children who are under 16 years old but already understand Bitcoin and how to utilize internet security, my guess is that these children have an IQ above average and need special guidance.
It is true that so far there is no age-limiting provision in terms of Bitcoin ownership, but guiding children who are entering their golden age is very necessary considering the swift flow of the internet that is unstoppable. If at that time we are able to guide internet security, it is not surprising that when the child's teenage years will easily understand when we teach about Bitcoin.
