Fiat-Backed Stablecoins: What You Need to Know About Tether, USD Coin and Others

A stablecoin is a term used to describe a category of cryptocurrencies that are pegged to the value of a fiat currency, such as the U.S. dollar, to maintain a steady value in the volatile world of cryptocurrencies. In other words, a stablecoin pegged to the U.S. dollar is designed to maintain a price of $1.

There are a few different types of stablecoins, including algorithmic stablecoins, cryptocurrency-backed stablecoins and fiat-backed stablecoins. A fiat-backed stablecoin simply means a government-issued currency like the U.S. dollar backs the stablecoin itself. In this article, we’ll focus on fiat-backed stablecoins and how they work.

What are stablecoins?

Stablecoins are cryptocurrencies whose value is pegged to the value of a fiat currency. They provide a way to store value within the cryptocurrency market without worrying about the fluctuations of cryptocurrencies like bitcoin (BTC). One use case for stablecoins is the ease of liquidating more volatile crypto assets into a more stable cryptocurrency to sidestep a correction or crypto crash. Instead of converting those cryptocurrencies to fiat currency, you can liquidate your digital assets into stablecoins and keep it easily accessible to re-buy into the same or other cryptocurrencies when you feel the time is right.

What are fiat-backed stablecoins?

Stablecoins are generally categorized into four different types: fiat-backed, commodity-backed, cryptocurrency-backed and algorithmic stablecoins.

The most popular types of stablecoins are “fiat-backed” meaning they are digital assets that have financial reserves in fiat currency held by a regulated institution like a traditional bank. In short, compared to its three other counterparts, fiat-backed stablecoins are truly backed by real-world currencies. These coins can be used to purchase goods and services online, just like any other cryptocurrency.

Unlike other cryptocurrencies, a stablecoin’s value is tied to the price of the underlying asset, and not supply and demand. For example, 1 tether (USDT) should always be worth $1, though market conditions can make it fluctuate slightly in reality. This makes them a more reliable form of currency for payments than other forms of cryptocurrency.

To purchase fiat-backed stablecoins, investors need to exchange their fiat currencies or other cryptocurrencies for them. When they want to sell their coins, they can exchange them for the corresponding fiat currency or use them to purchase other cryptocurrencies. Unlike other cryptocurrencies, fiat-backed coins do not require miners and do not use blockchain technology. Instead, they use centralized servers and rely on third parties to manage their transactions.
