Cryptocurrencies are known for their volatility and can fluctuate rapidly in value. This makes it challenging to use them as a store of value or a medium of exchange. Stablecoins were created to solve this problem by offering price stability. They are cryptocurrencies that are pegged to stable assets like fiat currencies, precious metals, or commodities. USDC and USDT stablecoins are the most popular representatives of this type of digital assets on the crypto market, but what exactly are they, and how do they compare? The comparison between USDC vs USDT offers insight into their unique characteristics and how they function within the crypto industry.

What are Fiat-Backed Stablecoins?

types of stablecoins
USDT (Tether) and USDC (USD Coin) are both stablecoins designed to be pegged to the value of the US dollar, meaning that their values are intended to remain stable at $1.

Fiat-backed stablecoins are the most common type of stablecoins. They are backed by fiat currency reserves held in a bank account. The amount of underlying fiat currency held in reserves should be equal to the number of stablecoins in circulation so that the stablecoin is fully collateralized. If the stablecoin is pegged to the US dollar, then it is referred to as a USD stablecoin.

Advantages of Stablecoins

Stablecoins offer a host of benefits, including their steady value, clear transparency, and high efficiency. These types of cryptocurrency are versatile, serving as a reliable store of value, an effective medium of exchange, or a consistent unit of account. They are particularly useful for cross-border payments, small-scale transactions, and remittances. Notably, USDT and USDC stablecoins stand out for facilitating low-cost, fast interactions and enabling users to accrue interest through decentralized finance protocols.

In comparison to traditional finance, stablecoins have several distinct advantages. Their decentralized framework allows for rapid, low-fee global transfers, circumventing the need for conventional financial intermediaries like banks. This aspect is especially appealing as it aligns with the increasing demand for stablecoins on major exchanges. Additionally, stablecoins offer enhanced security as an investment option, thanks to their foundation in blockchain technology, which ensures tamper-proof transaction records and safeguards user funds. Furthermore, many stablecoins adhere to regulatory compliance standards and undergo periodic audits, adding an extra layer of trust and reliability for users.

Why are there so many USD stablecoins?

The US dollar is the dominant global currency, and many people and businesses around the world use it for trade and commerce. USD stablecoins allow people to transact in USD without a traditional bank account. Additionally, they provide an efficient way to move money across borders, bypassing the fees and delays associated with traditional remittance services.

Stablecoins facilitate easy transfers and storage of value for users across cryptocurrency platforms, providing a safe option compared to the price volatility of such digital assets as Bitcoin and Ethereum.

What factors make a stablecoin safe?

The safety of a stablecoin is dependent on several factors, including its reserve assets, the level of transparency provided by the issuer, and the regulatory framework within which it operates. A stablecoin backed by a large reserve of a trusted fiat currency and audited by a reputable third party is considered safer than a stablecoin backed by an unknown asset or an unaudited reserve.

What Is Tether (USDT)?

Tether (USDT) is the oldest and most popular USD stablecoin that was launched in 2014 with the goal of creating a bridge between cryptocurrencies and traditional fiat currencies. It is pegged to the US dollar and backed by a reserve of fiat currency and other assets. Tether is the most widely used stablecoin, with a market capitalization of over $70 billion.

USDT Stability

In 2017, Tether was hacked, and 31 million USDT tokens was lost. The project got criticized as many point out that instead of taking responsibility and demonstrating accountability, they initiated an “emergency hard fork” to save face.

In 2017, Tether was hacked, and 31 million USDT was lost. Instead of taking responsibility and demonstrating accountability, they initiated an “emergency hard fork” to save face. This caught the attention of the New York Attorney General when it was discovered that Tether was lending out its cash reserves without being able to adequately back their tokens with USD. They attempted to absolve themselves of responsibility by antagonizing the Attorney General instead of providing a rational defense.

USDT Volume

According to CoinMarketCap, the current market capitalization of USDT is around $111 billion, and it is the most widely used stablecoin in the world. This makes Tether the third crypto asset by market capitalization, only surpassed by Bitcoin and Ethereum.

What Is a USD Coin (USDC)?

USDC, or USD Coin, takes second place in the list of the most popular stablecoins. It was launched in 2018 by Circle, a fintech company based in Boston.

The Centre consortium, which includes Circle and Coinbase, issues and manages USDC. Centre is the only entity that can control USDC supply, similar to the Federal Reserve controlling USD. However, there is a major difference between USD and USDC — Circle has full authority over USDC, which is not the case with USD and the FR.

USDC Stability

USDC Stability is considered to be more transparent than USDT because Circle provides monthly audits of its reserve assets. Additionally, USDC is regulated by the US Securities and Exchange Commission (SEC).

In March 2023, Circle reported that $3.3 billion of the cash reserves backing USDC tokens remained in Silicon Valley Bank, causing it to depeg and drop in value against the dollar to 87 cents. In addition, similar dollar-backed stablecoins such as DAI and USDD were depegged from their original value of $1. However, it only took USDC 2 days to return its peg.

USDC Market Capitalization

According to CoinMarketCap, the current market capitalization of USDC is over $32 billion, and it is the second most widely used stablecoin in the world after USDT.

USDC vs Tether: What is the difference between USDC and USDT?

They are both stablecoins

USDC and Tether are almost indistinguishable, differing in market cap. Both Tether and USD Coin are stablecoins, meaning they have a fixed value that is pegged to the US dollar. This makes them less volatile than other other crypto assets, so they can serve as a store of value or a medium of exchange. However, they cannot be treated as perfect substitutes for the US dollar since it’s impossible to deposit them into a bank account or use them for payments.

One-to-one (1:1) value ratio with USD

Both Tether and USD Coin maintain a one-to-one (1:1) value ratio with the US dollar. This means that for every USDT or USDC token issued, there is a corresponding US dollar held in reserves.

Blockchain variation

Both Tether and USDC stablecoin had operated solely on the Ethereum blockchain, but gained representation on multiple blockchains since then, which allows for rapid transferral and low transaction fees.

Blockchain transparency

Both Tether and USD Coin provide transparency in terms of their blockchain transactions. This allows users to track their transactions and ensure that they are getting what they paid for.

Rapid transferral

Both Tether and USD Coin can be transferred quickly and easily, which makes them ideal for peer-to-peer transactions and remittances.

USD Coin vs Tether: What are the Key Differences?

Tether vs USD Coin: What's the difference between USDT and USDC?
Is it better to hold USDT or USDC?

Tether (USDT) and USD Coin (USDC) are two of the most popular stablecoins in the cryptocurrency space. While both stablecoins share some similarities, there are also some key differences between them:

Launch date

Tether was launched in 2014, while USD Coin was launched in 2018. This means that Tether has been around longer and has had more time to establish itself in the market.

Reserve Assets

Both Tether and USD Coin are backed by a reserve of assets, such as fiat currency and other financial instruments. However, concerns have arisen regarding the stability and transparency of Tether’s reserves, as the company has faced accusations of using unbacked reserves to support the value of its stablecoin.

As of 2024, Tether (USDT) is primarily backed by U.S. Treasury Bills and other assets. According to Blockworks, approximately 58% of Tether’s reserves are held in U.S. Treasuries, with the remaining reserves consisting of cash and cash equivalents (about 9%), secured loans (around 9%), and various other investments, including crypto holdings, corporate bonds, funds, and precious metals. This diverse backing has drawn scrutiny and calls for greater transparency and regulation.

In contrast, USD Coin (USDC) is backed by a more straightforward reserve policy, primarily consisting of cash and short-term U.S. Treasuries. Around 75.6% of USDC’s reserves are held in U.S. Treasuries, while 24.4% remain in cash at regulated financial institutions. Circle, the issuer of USDC, ensures compliance with financial regulations by holding these reserves with regulated financial institutions.

Circle has earned public trust by maintaining a positive reputation and providing detailed disclosures about its reserve assets, while Tether continues to face controversy due to perceived opacity and unregulated centralization. Tether’s lack of transparency has been highlighted by its omissions regarding the specific composition of USDT’s backing, contrasting sharply with Circle’s commitment to regulatory compliance and openness.

Trade/liquidity volume

Tether has a much larger trading and liquidity volume compared to USD Coin. According to CoinMarketCap, the daily trading volume of Tether is around $60 billion, while the daily trading volume of USD Coin is around $6 billion — approximately ten times less. So, Tether is a more popular stablecoin for traders and investors.

USDC vs USDT: Concluding Thoughts

USD Coin, on the other hand, has been more transparent about its reserve assets. Yet, it has a smaller trading volume. Ultimately, the choice between Tether and USD Coin will depend on the individual needs and preferences of the user.

What is the difference between USD and USDT?

USD (United States Dollar) is the fiat currency issued by the Federal Reserve Bank in the United States. USD is a physical currency in the form of paper money and coins, backed by the US government and used as a medium of exchange for goods and services.

USDT (Tether) is a digital, blockchain-operated stablecoin created to remain pegged to the US dollar. It’s issued by Tether Limited and supposedly backed by reserves consisting of an equal amount of USD.

The key difference between USD and USDT is that USD is a physical currency that the US government issues and backs, whereas USDT is a digital currency. Instead of the government, it is backed by an equivalent amount of USD that Tether Limited holds in reserve. Additionally, while USDT intends to maintain a steady value of $1, the value of USD is subject to market forces like inflation and interest rates.
