According to a report by Bloomberg, Kenneth Rogoff, former chief economist of the International Monetary Fund (IMF) and member of the Federal Reserve Board, pointed out in an interview that the increasing geopolitical tensions and the rising influence of cryptocurrencies are continuously undermining the global position of the US dollar.

Kenneth Rogoff also rebutted the viewpoints of those who believe that cryptocurrencies are merely scams with no value, emphasizing that "it is a mistake to think that cryptocurrency trading has no 'fundamental value proposition'". He stated that the global underground economy once primarily used the US dollar as its preferred payment method, but it has now been replaced by cryptocurrencies. This is because cryptocurrencies provide a recognized medium of exchange, which makes it difficult for governments to strictly regulate and control the underground economy, indicating that cryptocurrencies "are not worthless".
