Paper silver is a kind of personal voucher silver and a precious metal wealth management product launched by banks. Investors operate on bank online banking, and there is no physical silver extraction and delivery. The price difference fee is 0.04 yuan. At present, except ICBC, all banks can only buy up and not buy down. As far as choosing the white bank is concerned, tomorrow is about 100, and paper and silver need a price difference of 0.4 cents, so paper and silver are only suitable for long-term operation, and it is not yet out of touch.
