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.
You already answered your own question. Bitcoin is permissionless and has no age requirements. There have been Bitcoin developers like Matt Corrallo, who were still teenagers when they started contributing. Vitalik was only 17 when he co-founded Bitcoin Magazine.
Despite having a young age, it is still possible to be very knowledgeable about Bitcoin. It might be more difficult to use some services which require KYC. These requirements are only imposed by centralized third parties. As long as Bitcoin is decentralized and you hold your own keys, anybody of any age is allowed to participate in the network.
