No need for teaching. Why set an age where should they learn? Preparation? That was crazy. It's not something that you need to prepare for 10 years lol.
Just watch them grow and let them encounter the things without us interfering with them. Trading is important but we should not force them to undergo trading without their interest in it. Soon, they will encounter it and will ask for help. That's the time we need to step in.
Indeed. It was great though that you will let your child decide what they really want. Watch them grow, let them be who they are but always teach them good lessons for them to learn. They might encounter trading and maybe ask questions about it or ask help for them to understand it. There's no need for us to force them about trading, let them explore and encounter it than introducing this to them because it may confuse them if we will introduce trading in a young age. If there's the time they will ask about it then it's the time we need to step in and help them understand about it.
