What exactly is fiat money?
If you're just getting started in the realm of cryptocurrencies, you might hear the word "fiat" used very frequently. Fiat money, often known as fiat currency, is money that a government has recognized as legal tender and that it supports. A "fiat" is merely an authorized or arbitrary order, according to the dictionary. Therefore, the government passes a decree stating that it is acceptable and legal to pay both public and private debts in USD, GBP, INR, EUR, or any other kind of world money.

Explaining the Fiat Money System
Governmental reserves, treasury, and central bank systems issue fiat money to be put into circulation. Fiat money is issued by governments and is not backed by precious metals like gold or silver. This poses a risk since nations frequently create excessive amounts of currency to boost their economies, which leads to inflation. Governments have the ability to enact laws that regulate supply, liquidity, and interest rates thanks to fiat money.
Money Supply Classifications for Fiat

M2 - This covers everything in M1, but also includes investments like mutual funds and savings deposits that can be swiftly converted into cash.
M3 - This category combines M1 and M2 with larger time deposits and less liquid institutional money market funds.
All cash and bank accounts are included in M4, which is the total amount of money.
