Those game are the worst games i don't know if you have ever tried them but those are literally filled with ads it was basically impossible for you to click the claim button as 3-4 banners pop up. If we actually had to teach are children about bitcoin we should encourage them to buy bitcoin using the their savings and tell them how the price of your initial money increased.It's true if we introduce it through the game because their orientation doesn't have to go directly to earnings, but your next opinion is also true, teach them how to make a wallet, and fill some small nominal btc to them. However don't teach them about this forum too early, because many negative aspects like gambling and betting, this aspect isn't wrong, just not good to be taught on your kids.
