Just because your child doesn't like it, doesn't mean no child will. Fortunately, children are like adults: as diverse as they are interesting. And nobody said anything about forcing a child to watch a cartoon, because that borders on the ridiculous.
Let me remind you once again that Monopoly is played from the age of 7/8 and that some children are particularly precocious. I thought the cartoons in the thread were really cool, and reminded me of a cartoon I used to watch when I was little.
You need to offer children as many things as possible, so that they can choose, open up to the world and develop their natural curiosity.
"There’s always the right time for everything" : it's very reductive ! Some children learn to read at two, others don't walk until 18 months, some like to read, others like video games. We see children playing salesmen in day-care centers and they start learning to count like that, for fiats it would be better than bitcoins when you play?
Forgive me for saying so, but the children in your families must be really bored.
Like I said, are you married and have kids? I tried it with my 2 sons and 2 grandchildren (1 boy and 1 girl). The results I got are the same, and what I am saying is what I have experienced with them, I am not speculating, and it is not even my opinion. What are you saying is your opinion, or have you applied it to your children and grandchildren? Moreover, I am not a person who likes to force anyone, especially my children, my parents let me grow up freely, and I want the same with my children.
I'm not saying I won't teach my kids bitcoin, but I think it will be appropriate as they get older, at least over 11 years old.
