My second grader daughter Phaedra is learning about money at school and she got interested in that small black box that on daddy's table when I told her that it prints out wallets that can hold a new form of money: Bitcoin.
See here how she interpreted what Bitcoin is: http://bitcoinowl.com/bitcoin-explained-7-year-old
I tried telling my 6 year old about Bitcoins... but the moment he realized "mining" had nothing to do with Minecraft, I think I lost his interest
Just sent a small tip.
Hehe, frikking minecraft.
