Coinbase CEO Brian Armstrong and French central bank governor François Villeroy de Galhau engaged in a heated debate over Bitcoin's role in the global monetary system at the World Economic Forum in Davos. Armstrong argued that Bitcoin serves as a crucial accountability mechanism against deficit spending, particularly in countries with high inflation like Argentina, Turkey, and Nigeria. He emphasized Bitcoin's fixed supply as a safeguard against currency debasement. Villeroy countered by defending the role of central banks in managing economies and maintaining democratic control over money. He expressed skepticism about Bitcoin replacing fiat currencies, highlighting the importance of public control in monetary policy. The exchange underscored the ongoing global debate over monetary control amid rising inflation and economic instability.
