How it's possible a 10-15 years old kid can create a new account on centralized exchange?
Trading simulator! What is more important is to get the concept of trading first-hand. The KYC and other legal stuff will come later on.
a kid doesn't need to learn about trading too because it's risky.
Unless otherwise they are given the correct information of what to do and what not to do in the first place. Come on! Life is big risk in itself.
In my opinion, it's not a bad idea to teach your friend kid about trading or finance in general, as long as they are given correct information on controversial topics like "money".
When I was 18 or 19, I learned the basics of trading and investing through an online game called
"CASHFLOW Classic" by Robert Kiyosaki. The premise of the game is to mimic real-life scenarios of growing your wealth from scratch. You are given a dream to escape the "rat race," and you must do everything you can to grow your money passively by earning through incomes, trading stocks, investing in properties, etc. I think this is probably the best approach to teaching someone the basics of "financial education" because it's more fun and enjoyable than diving into trading right away.
Afterward, your friend kid can use a trading simulator like this
basic one[2] and later progress to a more
complex[3] trading simulator. You can't just teach someone all the jargon involved in trading without them seeing a visual representation of what's happening when they buy a crypto/stock at a lower price and sell it later at a higher price.
