In the 21st century, money is no longer limited to bills, coins and credit cards. In fact, some money is truly international — not owned by any particular government — and regulated “by the people” instead of a central entity. It also exists wholly on the internet. This type of money is called cryptocurrency.
You may have heard of or even used Bitcoin when it first became popular several years ago, but where Bitcoin used to rule, other cryptocurrencies are now being used to pay back family members for lunch, charge customers for products and services and make other everyday transactions.
