Hi there to all of you. One of the most amazing things I've noticed about Bitcoin is that it doesn't have an age requirement before using it or creating a wallet. In traditional banking, however, one must be 16 or older to open an account, unless they have assistance from a guide who helped them do so. Additionally, no matter how young you are, no one can question you about how you make money because no one keeps an eye on your wallet.
There is no age limitation that can possibly be enforced. Bitcoin is completely open to all and not even the government has the power to prohibit it. All it takes is an internet connection.
Now as to the question of whether a parent imposed age limitation is wise:
Is a $1 dollar bank note alright for children to have? What about $10? $100? Of course it is alright for them to have and spend and do whatever they want with it, but whether or not the child has been educated on how to use it and spend it responsibly is the parent's job. Teach them about Bitcoin and how to use it responsibly.
