肯●罗格夫 （Ken Rogoff）

In his book The Curse of Cash, leading economist Ken Rogoff suggests that excessive reliance on paper money is responsible for ills ranging from tax evasion to terrorism. He also believes that monetary policy would be more effective in a largely cashless society. Cryptocurrencies are not an effective replacement for paper money, he says, but gold’s role is likely to increase as cash fades from view.
