If my kid is still too young, I wouldn’t teach them about Bitcoin yet as they likely won’t be interested anyway. And honestly, it’s too risky for them to learn about it early on, especially once they start earning. That could easily lead to gambling behavior, which isn’t far off when you're dealing with volatile assets.
IMO, there’s a right time for everything. Since Bitcoin is a high-risk investment or asset, it shouldn't be introduced at a very young age. Let kids be kids first... when they grow up and mature, that’s when they’ll be better equipped to understand and handle things like Bitcoin responsibly.
Your decisions will be okay by you because as for me 13 years is a good age bracket enough for me to start introducing Bitcoin to my kids, I believe if they start leaning especially the basics before getting to 18 they will become more grounded with Bitcointalk knowledge including the potential risks and benefits, if kids grow up to a certain point where they are even earning it also means that they are are very much responsible for their actions and reactions, the only thing you can do is to guide them ass much as you can while they have their final decision.
