ETH en USD : 1 Ethereum équivaut à USD

The United States Dollar (USD) is the currency used in the United States. It provides a unit for local prices, wages, savings and business accounts, helping households and businesses compare the value of goods and services. The code USD identifies it in international quotations and financial records. Currency issuance and monetary administration are overseen by the Federal Reserve System. The currency is used through cash, bank balances and electronic payments within the local financial system. Its economic setting includes services, manufacturing, trade. It is a major global reserve currency and a common unit for international invoicing and commodity pricing. An exchange rate measures its value against another currency, while domestic inflation affects what it can buy locally. Import costs, overseas receipts and monetary conditions help explain why these two measures can move differently. In cryptocurrency markets, USD can serve as a familiar reference for asset prices and portfolio values. A price expressed in USD is a valuation, rather than a guarantee of a payment or trading channel. The fiat currency is separate from stablecoins or other blockchain tokens that may reference its value.
