What Are Stablecoins? Definition and How They Work

Contrary to the general volatility of many cryptocurrencies, there exists a subset designed to maintain a consistent value known as stablecoins

Stablecoins are a type of cryptocurrency that is designed to maintain a stable value, usually by being pegged to a real-world asset such as the US dollar. The purpose of stablecoins is to mitigate the volatility of other cryptocurrencies like Bitcoin and Ethereum, which can experience rapid changes in value.

To fully grasp the potential of stablecoins and how they interact with more volatile cryptocurrencies, it’s important to dive deeper into their workings. CoinMinutes has an informative article that can help you understand Stablecoins better.

What Is Stablecoin?

Stablecoins represent a category of altcoins in a cryptocurrency realm that aims to establish price stability. Although its values can be pegged to various underlying assets, its primary objective is to uphold a consistent value even amidst the broader fluctuations of the cryptocurrency market.

Difference Between Stablecoin and Other Cryptocurrencies

Here are the main differences between stablecoin and other cryptocurrencies:

Stablecoin Other Cryptocurrencies
Value StabilityDesigned to maintain a steady value, often pegged to another asset like a fiat currency, commodity, or algorithmic mechanism.Can experience significant price fluctuations, resulting in both potential high returns and high risks for investors.
Use CasesPrimarily used for practical transactions, including remittances, and as a medium of exchange within the cryptocurrency ecosystem. They provide reliable means to transact without being overly affected by price changes.Serve a broader range of use cases as a store of value, investment, and utility tokens within specific platforms.
Underlying AssetsTypically backed by assets like fiat currencies, commodities, or collateralized by other cryptocurrencies. These underlying assets contribute to their stability.Do not necessarily have an underlying peg to external assets. Their value is often determined by market sentiment, technological developments, adoption, and other factors.
Market DynamicsCreated to address the volatility issue in the cryptocurrency market, aiming to provide a more reliable and predictable form of digital currency.Contribute to the dynamic nature of the cryptocurrency market, being subject to rapid price changes influenced by various factors.

Types of Stablecoin

Four categories of stablecoins exist, differentiated by the mechanism used to stabilize their value.

  • Fiat-Collateralized Stablecoins

Fiat-backed stablecoins ensure their stability by holding a reserve of a fiat currency, often the U.S. dollar, as collateral. Alternative collateral options may encompass precious metals like gold or silver, as well as commodities such as crude oil. However, the majority of fiat-backed stablecoins predominantly rely on U.S. dollar reserves.

These reserves are managed by independent custodians and undergo routine audits. Well-known stablecoins like Tether (USDT) and TrueUSD (TUSD) are examples backed by U.S. dollar reserves, maintaining a one-to-one parity with the dollar.

  • Commodity-Backed Stablecoins

Commodity-supported stablecoins are digital currencies that derive their stability from commodities like gold, real estate, or metals, which they hold as collateral. Among these commodities, gold tends to be the most widely favored asset for backing commodity-supported stablecoins. Notable instances of such coins are Paxos Gold (PAXG) and Tether Gold (XAUt). These particular stablecoins enable holders to engage in the gold market, offering the advantages of cryptocurrencies while sidestepping the complexities of owning physical gold bars.

  • Crypto-Collateralized Stablecoins

Stablecoins backed by cryptocurrencies rely on alternative digital assets for support. To counteract potential volatility, these coins adopt an over-collateralization approach. This strategy entails maintaining cryptocurrency reserves that exceed the total value of the stablecoins issued.

For instance, to mitigate the impact of potential price fluctuations, a reserve cryptocurrency valued at $2 million might be used to create $1 million worth of a crypto-backed stablecoin. This precaution guards against a 50% reduction in the reserve cryptocurrency’s value. MakerDAO’s Dai (DAI) offers an illustrative example: Though pegged to the U.S. dollar, DAI is backed by Ethereum (ETH) and other cryptocurrencies collectively valued at 150% of the circulating DAI.

  • Algorithmic Stablecoins

Algorithmic stablecoins operate with or without holding reserve assets. What sets them apart is their methodology for preserving a stable value—this is achieved by meticulously managing the coin’s supply through an algorithm, essentially a predefined computer program.

This approach bears a resemblance to central banks, which also uphold currency value stability without necessarily relying on reserve assets. The contrast lies in how a central bank like the U.S. Federal Reserve openly establishes monetary policy based on well-defined criteria, benefiting from the inherent credibility as the issuer of legal tender.

Why Are Stablecoins Important to Cryptocurrency?

Stablecoins are essential to the cryptocurrency ecosystem for their ability to provide stability in a highly volatile market. They serve as a reliable gateway between traditional finance and cryptocurrencies, facilitate trading, empower decentralized finance (DeFi), enable cross-border payments, offer a reference for market pricing, aid in risk management, and drive financial innovation.

How Do Stablecoins Work?

Stablecoins strive to align their market value with an external reference, commonly a fiat currency. They serve as a more practical medium of exchange compared to cryptocurrencies with higher volatility. Stablecoins can be tethered to a specific currency like the U.S. dollar, linked to the value of commodities like gold, or governed by algorithms that regulate their supply. Additionally, they may incorporate reserve assets as collateral or utilize algorithmic mechanisms designed to manage their supply.

Examples of Stablecoins

Several stablecoins have gained popularity in the cryptocurrency market due to their stability and utility. Some of the most popular coins include:

  • Tether (USDT): Tether is one of the earliest and most widely used stablecoins. It’s pegged to the U.S. dollar and maintained by Tether Limited. USDT is often used for trading and as a bridge between traditional and crypto markets.
  • USD Coin (USDC): USD Coin is a stablecoin issued by Circle and Coinbase. It’s also pegged 1:1 to the U.S. dollar and has gained significant adoption in the cryptocurrency ecosystem, including within DeFi platforms.
  • DAI: DAI is a decentralized stablecoin created by the MakerDAO project. Unlike other stablecoins, it’s not directly backed by fiat reserves. Instead, DAI is generated through smart contracts and collateralized by cryptocurrencies like Ethereum (ETH).
  • TrueUSD (TUSD): TrueUSD is a stablecoin backed by U.S. dollars held in escrow accounts. It aims to provide transparency and accountability through regular third-party audits.
  • Binance USD (BUSD): Binance USD is issued in partnership with Binance and Paxos. Similar to other stablecoins, BUSD is pegged to the U.S. dollar and used for trading on the Binance platform.

What Are Stablecoins Used For?

  • Minimize Volatility: Stablecoins aim to reduce the inherent volatility seen in cryptocurrencies like Bitcoin and Ether, which can fluctuate rapidly. These assets pegged to more stable currencies, provide assurance to traders and investors that their token values won’t experience sudden and unpredictable surges or crashes in the short term.
  • Trade or Save Assets: Holding stablecoins doesn’t require a bank account, and their seamless transferability makes them a convenient choice. Their value can be effortlessly sent across borders, even to regions where accessing U.S. dollars might be challenging or where the local currency remains unstable.
  • Earn Rewards: There are easy ways to earn rewards (typically higher than what a bank would offer) on a stablecoin investment.
  • Transfer Money Cheaply: Remarkably low transfer fees have enabled individuals to send amounts equivalent to a million dollars in USDC with transfer costs below a dollar.
  • Send Internationally: The rapid processing and low transaction fees make stablecoins like USDC a good choice for sending money anywhere in the world.

Why Do People Choose Stablecoins Over Other Coins?

People opt for stablecoins over other types of cryptocurrencies for several reasons:

  • Reduced Volatility: Stablecoins offer a stable value, which is particularly appealing to those who want to avoid the price volatility associated with other cryptocurrencies like Bitcoin and Ethereum. This stability makes stablecoins more suitable for everyday transactions and as a store of value.
