I have several kids 11 and under.

I'm teaching them about bitcoin by giving each of them their own lightning wallet. When they do some work, they get paid in their lightning wallet. When they want to buy something "with their own money" its deducted from their balance. When they fight with one another, intentionally break something, or refuse to do their homework they have to pay us or their siblings out of their wallet.

I just finished setting up my bitcoin lightning node for the family using lndhub/bluewallet. They already are informed on how to use it to settle balances. This solves the problem of kids going into each others things and mixing up, losing, 'borrowing' their money. They're using real BTC so they will eventually be able to buy things on the internet when adoption improves. In the meantime, I act as their fiat exchange.

A LndHub/Bluewallet compatible chrome extension called Alby is available for the kids (they aren't allowed on phones). Alby is relatively new and under active development. Hopefully it'll be able to act as their full-fledged wallet. They can see their balance in Sats, create and pay invoices denominated in SATs and can watch what they're doing from my phone.

The kids have the freedom to control their own account, they can create invoices and pay them. There's no longer any need for them to have social security numbers, they can be unbanked their entire lives if they so choose. Maybe when they're adults they'll think their old man was a crazy anarchist and want to drop themselves into the machine, but at least they'll have the opportunity to see the world differently than most. On the other hand, they'll have a major jump on their peers with regard to understanding money and cryptocurrencies and how to thrive outside the old and corrupt ways.

I was trying to figure out a way to make them take interest in the current price of bitcoin, and had already explained to them the "HODL Bank" perspective that it will eventually be a very large number. Given constant fluctuation in price, my thought is this may or may not be the long-term norm and they should get used to it at a young age since the US Dollar will probably coexist with bitcoin indefinitely as parallel world-reserves.

So this is what I did and its working brilliantly:

We homeschool and don't own a television, so our kids had never heard of daytime TV game shows (live television is for old-fogies).

I asked the oldest to try to guess the price today. He gave a half-hearted answer and said 3280 (thinking I meant the number of Sats per dollar). I asked another and they shrugged their shoulders.

Who would have guessed hours of watching Bob Barker with his silver microphone would actually turn into a life-skill some day as an adult? I called all of them to the table and said "OK, I'll pay you one dollar if you can guess the price of bitcoin today, but if you go over you lose, nobody can guess the same price, and you can pick something only a dollar higher than another person and essentially steal their guess.

You have no idea how excited they got and now they want to do it every day! We've been doing it for two full weeks and everyone looks forward to playing. Whoever finishes their nighttime chores first gets to be the last bidder.
