 Toddlers invent money in kindergarten, blocks and rubber bands and Pokemon cards and other little tokens, abstractions of value, that they exchange to strengthen social bonds, to express loyalty and friendship. To learn about sharing, children will be building currencies. Only this time, these currencies will be global, unforgeable, and scalable on day one. A few years from now, Maria will be launching Maria Coin in her kindergarten, to compete against Joey Coin. Until Justin Bieber launches Justin Bieber Coin, and it happens to surpass the market capitalization of 30 nations on this planet.
