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
What do you think?
If your children are tech savvy at age 10 maybe as a result of exposure, telling them or introducing them to the market without enforcing them to do so at the detriment of the childhood and experiences is a good idea to me.
At that age, children are very excited and curious about technology, the internet and electronic devices, so instead of letting them know the entertainment part of technology ( video games, cartoons, movies, internet etc) alone, it is best you also tell them or even show them about the most important part, the part where you can make money from as well which is trading (Crypto or forex) and others.
This early introduction will serve as a sensitisation to them that will awake an interest more as they grow.
