cash（cashmere是羊绒还是羊毛）

cash

Cash is a form of money that can physically exist in the form of coins and paper banknotes. It is legal tender that can be used to purchase goods and services and is sometimes referred to as hard or soft currency.

Cash is normally divided into two types: coins and banknotes. Coins are metal discs, often composed of copper, nickel, and other metals, that have every denomination of currency attested to by a government body. These are usually issued in physical form and are accepted universally. Banknotes on the other hand are usually prints of paper notes, often with pictures or writings of historic or cultural significance, which also carry denominations of various currencies, though these can vary from country to country.

Cash is the oldest form of exchange and has been used for thousands of years. Historically, coins were a form of metal exchange. These were then replaced by banknotes when it became too difficult to transport coins from place to place. During the Middle Ages cash was used for trading, paying taxes, and other economic transactions. With the advent of banking and the use of paper money, cash also became a viable alternative to metal coins.

Today, cash is generally accepted as a form of payment everywhere and it is easy to exchange for goods and services. It is also seen as a safe and secure way to store value. Cash transactions can be made almost instantly, eliminating the need to wait for a cheque to clear or wait for a bank transfer.

The convenience of cash also means that it is not subject to the same levels of regulation as other forms of payment. As a result, it can be used to carry out illegal activities such as money laundering and tax evasion. It is also more difficult to trace than other forms of payment, making it harder to control and regulate.

Cash is an important medium of exchange that is used regularly and accepted in most places. It is also an important form of liquid asset for those who need to access funds quickly and without difficulty. However, it does pose several risks and it is important to take precautions when using cash.
