"Bitcoin represents a monumental paradigm shift that will transform the social, political and economic landscape," according to Paul Vigna and Michael J. Casey in this presentation. Since its advent, Bitcoin has gained a reputation for instability and illicit business; naysayers fear its power to eliminate jobs and upend the concept of a nation-state. Vigna and Casey show that cryptocurrencies can also bring good. For one, they remove the middleman from the financial system, giving the power to the people and safeguarding from the devastation of a 2008-type crash. They also promote financial equality; Bitcoin has already given the world’s unbanked - those marginalized billions who’ve never had a bank account - unprecedented access to the global economy.
