billionaire

A billionaire is a person whose net worth or total wealth exceeds one billion units of currency, most commonly dollars, euros, or other major currencies. This valuation includes the value of their assets such as businesses, property, investments, and savings, minus any debts. Being a billionaire indicates an exceptionally high level of wealth, usually accumulated through successful entrepreneurship, investments, inheritance, or a combination of these. Such individuals often influence markets and economies, and their wealth places them among the richest people globally.
