Money
Money is a medium of exchange that is widely accepted in transactions involving goods, services, or debts. It serves as a unit of account, a store of value, and a standard of deferred payment. Money comes in various forms, such as coins, banknotes, or digital currencies, and plays a crucial role in the functioning of modern economies.

Functions of Money
Money serves three main functions in an economy:
1. Medium of Exchange: Money facilitates the exchange of goods and services by eliminating the need for barter. It allows for more efficient transactions, as individuals can easily trade using a universally accepted medium.
2. Unit of Account: Money provides a common measure of value that allows for the comparison of prices and the tracking of economic transactions. It enables individuals to assess the worth of goods and services in a standardized manner.
3. Store of Value: Money can be saved and used for future purchases, making it a reliable store of wealth. It retains its value over time, unlike perishable goods, making it a convenient way to hold and transfer wealth.

Types of Money
There are various forms of money, including:
- Commodity Money: Money that has intrinsic value, such as gold or silver.
- Fiat Money: Money that is declared legal tender by a government, such as paper currency.
- Digital Money: Money that exists only in electronic form, such as cryptocurrencies like Bitcoin.

Importance of Money
Money plays a crucial role in the economy by facilitating economic transactions, promoting specialization and trade, and serving as a stable medium of exchange. Without money, the economy would rely on inefficient barter systems, limiting economic growth and development.
