I want to know if it right for children that are of 10-15years go in to trade or not because I have a kid friend of about 14years and very eager to learn trading but am scared of the lost and how long it will take him to understand what his doing, because it hasn't been very easy for me. So what your opinion please I need help? because I think is too risky for them to go in to trade for now.

I hope you don't teach him. I know they must be curious about making money trading. but at that age, they don't have financial strength yet. the money they get is also the result of gifts from their parents. this will be bad for him and also you and even the parents of your childhood friend.

maybe you can teach him about Bitcoin investment. It is better. Bitcoins can be purchased in small amounts, depending on the ability of the remaining money that he can save for a long time. although still not recommended until they have clear sources of finance.

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.

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.

Learning is fine, however I am quite sure that in order to open an account at a CEX you need to be of legal age where you reside, so trading knowledge is not of much use to someone so young, what you can do is to teach him more about the history of money and the economy in general, things like money management, inflation and the way the fiat system work could be more helpful to the kid now, and eventually you could teach him how to trade, so when he finally can open an account at an exchange not only he will know how to trade but he will have some money saved already in order to start their journey immediately.

It's not an issue, and it's a good learning point at that age on how he can save his money and spend it wisely. If ever he has some savings and he'd rather use it on trading then, what is wrong with that? It's better than just buying the premium on some console games, and who knows if he could increase his money by trading.
I say, just guide him. You should not stop a kid that is already willing to do it, maybe he is just different from others and just needed some guidance to learn more. I'd prefer that way, than gambling or spending in Robux which most kids play now. There are no returns from those platforms.

Trading will also turn into gambling if you trade without any knowledge. At the age of 15, he already knew about money, and what the boy wanted was to make money fast, not seriously learn about trading. This age should focus on learning, if you teach him about trading, he will probably neglect to learn. As OP said: he doesn't want to lose the original amount, which means he is still using his parents' money. If he loses, it's easy to steal money from his parents. There are more disadvantages than benefits to letting a 15 year old know about trading.
