I think this is not the best time to teach our kids about bitcoin,for example they are playing games and earning bitcoin and they already reached the minimum for withdrawal but they didnt get paid cause the game is scam. This will be affecting thier interest to bitcoin and the hurt it brought to them which they can never forget
You are right. A child shouldn't play scam games. If a game was setup to teach children and was not a scam that would be great. But think about it you can't teach a child about bitcoin untill they understand the value of money. There more important things to teach them first. You need to have the stepping stones to get to eventually teaching bitcoin. Maybe when the child is in their teens or preteens ?
I don't see issues if children play scam games, of course it's very nasty, but they are learning another lesson simultaneoulsy to Bitcoins: life is fully of scammers and thieves. Better to be scammed when a child and lost $1 than be scammed later and lose $1000... When they become adults they will be protected and aware against scam offers.
