"Governments of the advanced industrial economies should phase out the use of paper money in the form of large-denomination notes and sharply restrict the use of cryptocurrencies."

That was the resolution at a public debate hosted by the Soho Forum on December 3, 2018. Arguing the affirmative was the Harvard economist Kenneth Rogoff, a former chief economist at the International Monetary Fund. Lawrence H. White, a professor of economics at George Mason University and a senior fellow at the Cato Institute, argued against the resolution. Soho Forum Director Gene Epstein moderated the debate.
