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 in Bitcoin just like bank will have 16years upwards and the old may not be able to handle transaction at old age. It's not thesame thing to Bitcoin too. Bitcoin. For example bitcoin transaction need who is educated and can operate the wallet without a third party. The third party is the cause why bank has a rule which restricts underaged persons. That is the important of decentralization.
As long as the person getting into bitcoin can understand it then there isn't much issues and age wont be a limitation.
And there is also a level of responsibility that this kids needs to accept to be in bitcoin, like to be cautious to not send bitcoin to a wrong address and also if considering to invest in bitcoin they is also a level of knowledge they should have in oder not to mess things up so early.
So IMO it's not a matter of age but of responsibility and if theat child is willing to not be playful around bitcoin then he is good to go.
