Cash is almost extinct.
From the white paper:
While cash use in the United States fell from 40 percent of transactions in 2012 (12 percent by value) to 19 percent in 2020, other countries have seen more rapid declines. In Sweden, for example, the proportion of cash payments fell from 33 percent to less than 10 percent over the same period. In China, 50 percent of point-of-sale (POS) payments are made with a mobile wallet or app, while cash accounts for just 13 percent of POS payments. If these trends were to emerge in the United States, consumers might want the option of digitized central bank money that, like cash, would have no credit or liquidity risk attached to it.
