This forum rules never talk about any age requirement for the forum, is it right to bring in a 13 years old on the forum or not? He seems interested in crypto and he wants to learn, I believe he will know a lot through this forum than going online for answers. Good move or nah?
What do you mean by
bringing 13 years old kid?
Are you his parent?

And how do you know he is interested in crypto? Do you teach him about crypto or he knows it himself?
If you teach him about crypto, it is not his own interest but you lead him to feel interested in crypto. You are too early to let him know about crypto.
Anyway, as far as I know there is no age limitation in this forum. But this forum is surely not for kids, the topics we are discussing here are not kids' stuff related. I doubt the kids misunderstand the information, or they feel confused about the topics here.
I think it is not the right time for him to join this forum. If you are familiar with crypto, you can teach your kid about it. Just focus on basic things only, don't force him to know something that doesn't suit his age. Let him know about this forum when he is mature enough, so he can use this forum properly and wisely.
