In just a few years, cryptocurrencies, like Bitcoin, have emerged from near obscurity to a prominent place in the financial landscape. Major financial firms are now actively engaged in the development and promotion of Crypto products, and governments around the world are struggling with development of a regulatory framework to ensure that Crypto does not undermine the safety and stability of the financial system. This course will provide a nontechnical introduction and overview of Crypto, focusing on what Crypto is and how it works and on the broader implications of Crypto for the financial system.
