Confused about cryptocurrencies, like bitcoin or Ether (associated with Ethereum)? You’re not alone. Before you use or invest in cryptocurrency, know what makes it different from cash and other payment methods, and how to spot cryptocurrency scams or detect cryptocurrency accounts that may be compromised.

What is cryptocurrency?

Cryptocurrency is a type of digital currency that generally exists only electronically. You usually use your phone, computer, or a cryptocurrency ATM to buy cryptocurrency. Bitcoin and Ether are well-known cryptocurrencies, but there are many different cryptocurrencies, and new ones keep being created.

How do people use cryptocurrency?

People use cryptocurrency for many reasons — quick payments, to avoid transaction fees that traditional banks charge, or because it offers some anonymity. Others hold cryptocurrency as an investment, hoping the value goes up.

How do you get cryptocurrency?

You can buy cryptocurrency through an exchange, an app, a website, or a cryptocurrency ATM. Some people earn cryptocurrency through a complex process called “mining,” which requires advanced computer equipment to solve highly complicated math puzzles.

Where and how do you store cryptocurrency?

Cryptocurrency is stored in a digital wallet, which can be online, on your computer, or on an external hard drive. A digital wallet has a wallet address, which is usually a long string of numbers and letters. If something happens to your wallet or your cryptocurrency funds — like your online exchange platform goes out of business, you send cryptocurrency to the wrong person, you lose the password to your digital wallet, or your digital wallet is stolen or compromised — you’re likely to find that no one can step in to help you recover your funds.
