The difference between currency, paper money and virtual currency (high school politics) is helpful. .

Money is a commodity, its essence is a universal equivalent, generally precious metals such as gold and silver, which have use value and value; Paper money is a kind of currency symbol, which has no value except its use value, so paper money is not money. Similarly, the grabbing form of virtual currency can be completely similar to paper money, which is not money. . . . Oh, I still remember that I specifically asked if coins were money before, and I added, well, no, because the raw materials for making coins are not precious metals.
