Well, the answer is yes, a minor can actually get involved in Bitcoin at a young age, but the way they got involved also depends on their age restrictions and parental guidance. And their purpose of getting involved in Bitcoin also matters, weather the focus is on learning, earnings, investing or trying to find a quick means of getting rich.
Studying or understanding technology, blockchain or how cryptographic works, doesn't require age limits, as long as your brain is capable, because at 16 a boy can be even more intelligent than someone in their twenties, so it all depends on their brain capacity. In as much as it doesn't require any age limit, but you must be smart, at least you should be able to read and write properly..I know a lot of people will disagree with me, but I want you all to understand that this minors are being initiated into criminal gangs to commit crimes at such age. In these criminal gang age doesn't really matters, so in Bitcoin, we should also find it suitable to let minors get involved in Bitcoin at this early age. This will help them understand that you don't have to get involved in crimes at such a young age to make money, they should be taught that money can be made through legal and legit means.
If this kids start buying Bitcoin at such a young age, they will be able to build and secure a bright future in their twenties. You can start with small amounts, you don't need to have huge capital, start from small and grow your account, in five to ten years, you will be smiling. It might be stressing, due to the school pressure, home pressure and all of that. This is why I recommend that only the smart ones should get involved. Bitcoin will teach them patience, consistency and emotional control abilities. At such a young age, their brains are still very young, they can be able to learn very quickly, because they won't even see it as stress or too much work, they will see it as a challenge, a test or just something they can use in keeping theirselve busy. Once their brain is well constructed and wired, they will definitely do well. Yes, they will make mistakes, but it is better to make mistakes at an early age than in old age.
I know there are disadvantages, I will need y'all to list and write them down below. I'm only focus in promoting Bitcoin and the advantage of it.
I don't see a problem with minors learning about Bitcoin, but I think the focus should be education rather than making money. Understanding wallets, private keys, security and how Bitcoin actually works can be valuable at any age. The financial side should come with proper parental guidance.
