People in the Fed would say this. Why? Because the whole fiat money system worldwide is a Ponzi. When people want to trade money for other things, what they want to trade is value. They don't really care what means is used. They simple want to trade value for value. The fiat money system is a method to steal value from people who use fiat to do the trading. Fiat is all the things that the Fed Chair says crypto is. - It's like two people facing off in a battle. One has a gun, the other has no weapons. Fiat is the gun that the Fed has. People have no weapons even though they use fiat. Crypto is like giving the people a gun.
