The BTC School in Brazil, is an innovative educational project focused on teaching elementary school children to use Bitcoin. This initiative, part of Brazil's Bitcoin Beach Citadel, allows students to purchase items like fruit using a debit card and a point of sale based on the Bitcoin Lightning network. The project aims to create a local economy based on Bitcoin, moving away from fiat money. The children use mobile point of sale technology from Breez Technology and a Bolt Card for Bitcoin payments from CoinCorner. This initiative is part of a larger plan to grow the Bitcoin circular economy in the area and to educate the community, especially children, about the benefits and practical applications of Bitcoin.
