For me at age 10 my children should understand the market and how it works, interpreting chats and deciding the next move of each coin from studying the price action of different coins. At age 13 the should start trading with a demo account and at age 15 they should have funded their first account. This would help them become financially independent, also help then limit future gambling prowess and also make them prepared for their careers
Funds has been one of the limiting factors many people encountered while pursuing their dreams and ambitions. For me I see it as means where the could comfortably fund their ambitions without much stress and still have enough for fun and recreation.
When I was 6-7 years old, computers were not a thing that was abundant in every house, most companies had it but it wasn't in houses too much yet, sure there were some people who had it, but it was early 90's in a third world nation so it wasn't very common, probably like 10% of the people had it, so it was a rare thing to have a computer in your house and let alone just so that your kid play computer games, that part was seriously rare, nearly nobody bought a computer to let their kids play a computer game.
So, one day after I played some computer games at my mom's work which had a PC, I came home and told my dad I wanted a computer, and he told me he would buy one if I could get the initial money, which was about 200 bucks, and computer was around 1200 bucks, so after you paid the 200 at first, the other 1000 became a 100 per month for 10 month thing.
What did I do? I worked hard and went to everyone I know and did child work, like bring them groceries, get then newspapers, and many other things, even sold small stuff with the capital I had to make it bigger, I made it in under 3 months and gave it to my dad who was shocked, he thought it would be impossible and that is why he said it, couldn't believe I made that when I was 7 years old, so that is how I got my first ever computer at age 7, when nobody else had a computer at that age (not that I did anything with it, just played games and never helped me in the future). I want my kids to be like that, I was always good with money ever since that age.
