Maybe kids interested with games , so publisher can make game to educate about bitcoin.
Definitely. Playing chopcoin or battlecoin isn't really good for their overall development in my opinion, as they are gambling games and they should not be exposed to a bunch of adult only sites at such a young age.
But faucets, I think they are child friendly.
I think games is one of some good choice there but it have reallynbad efdect for them knowing it can teach them to gamble and they can develop low self confidence if we really push our kids to earn bitcoins in their this early situation, but if they are really interested maybe guide them properly and give some good advice so they cannot learn bad with bitcoins.
