| 簡介： | Thousands of years ago, the Mesopotamia tribes began an early form of trade and exchange called bartering. Today, people trade cryptocurrencies in exchange for clothing and food. In some ways, the riveting world of exchange has evolved; but in others, this world remains the same. Readers will encounter incentives for voluntary exchange (Standard 5), commonly traded goods and services, payment methods, barriers to trade, and international trade agreements. Compelling sidebars highlight exchange-related concepts, like Bitcoins, Silk Road, and the Consumer Boycott from the Anti-Apartheid Movement. |
