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?

What are Fiat-Backed Stablecoins?

Fiat-backed stablecoins are the most common type of stablecoins. They are backed by a reserve of fiat currency held in a bank account. The amount of fiat currency held in reserve 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
The advantages of stablecoins include stable value, transparency, and efficiency. Stablecoins can be used as a store of value, a medium of exchange, or a unit of account. They can be used for international money transfers, micropayments, and remittances. USDT and USDC stablecoins enable everyone to interact inexpensively and swiftly while also earning interest on decentralized finance protocols.
On the other hand, stablecoins provide numerous advantages compared to fiat currencies. Due to their decentralized nature, these crypto assets can be transferred around the world quickly and with minimal fees since they do not go through traditional intermediaries like banks. Also, they are a secure investment option because they are based on blockchain technology which creates immutable records of transactions and protects user funds against theft or loss due to unforeseen circumstances.
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
One of the main reasons why Tether has become so popular is because of its stability. The value of USDT is pegged to the US dollar, meaning that for every USDT token issued, there is a corresponding US dollar held in reserve. This ensures that the value of USDT remains stable, and users can easily convert their USDT back into US dollars at any time.
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 $72 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 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 Volume
According to CoinMarketCap, the current market capitalization of USDC is over $40 billion, and it is the second most widely used stablecoin in the world after USDT.
Tether vs USDC: Comparative Analysis
An analysis of the differences between Tether and USD Coin can be helpful. Both are stablecoins, though they have some different key features and should each be examined before investing. Let’s start with the similarities they share.

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 cryptocurrencies, 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 reserve. However, as we mentioned earlier, Tether tokens are not entirely backed by fiat now. In 2021, Tether’s team made an announcement on their website, saying: “Every tether is always 100 percent backed by our reserves, which include traditional currency and cash equivalents and, from time to time, may include other assets and receivables from loans made by Tether to third parties, which may include affiliated entities (collectively, “reserves”). Every tether is also 1-to-1 pegged to the dollar, so 1 USDT is always valued by Tether at 1 USD.”
Blockchain variation
Both Tether and USD Coin 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 (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 asset stability
Both Tether and USD Coin are backed by a reserve of assets, such as fiat currency and other cryptocurrencies. However, there have been concerns about the stability of Tether’s reserve assets, as the company has been accused of using unbacked reserves to support the value of its stablecoin.
Circle has earned public trust by maintaining a positive reputation, while Tether is mired in controversy due to unregulated centralization. Tether lacks transparency, as evidenced by its omissions about how USDT is backed.
Trade/liquidity volume
Tether has a much larger trade and liquidity volume compared to USD Coin. According to CoinMarketCap, the daily trading volume of Tether is around $80 billion, while the daily trading volume of USD Coin is around $11 billion. This makes Tether a more popular stablecoin for traders and investors.
USDC vs USDT: Concluding Thoughts
Stablecoins are essential to the crypto ecosystem, as they are blockchain-based tokens with a stable value linked to fiat currency. Stable tokens ensure users can conveniently transfer and hold value across various crypto platforms without the exposure to price fluctuations common in digital assets such as Bitcoin and Ethereum. USDT, USDC, and BUSD (Binance USD) form the bulk of the stablecoin sector’s market cap, making them ideal choices for investors looking to become part of the stablecoin market.
Overall, while both Tether and USD Coin are stablecoins designed to maintain a 1:1 value ratio with the US dollar, there are some key differences between the two. Tether has a longer history and a larger trading volume, but it has faced some controversy over the stability of its reserve assets. 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.
USDT vs USDC: FAQ

Is USDC safer than USDT?
Some investors consider USDC a safer option than USDT, as it is more transparent and regulatory-compliant. Its periodic audits and real-time reports on reserves provide assurance that the token is backed by actual assets. Conversely, USDT has been met with scrutiny due to doubts surrounding its reserve backing and transparency.
Why is USDT higher than USD?
USDT is a stablecoin pegged to the US dollar, meaning its value should be equal to that of the USD. Demand for USDT can, however, at times exceed its available supply and cause the price to go higher than USD. The price of USDT is additionally determined by market forces such as supply, demand volume, and market sentiment.
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.
Why do we use USDT instead of USD?
USDT is often used in cryptocurrency trading instead of USD due to its stability and convenience. Additionally, it is widely accepted among cryptocurrency exchanges and offers a faster way to move funds than traditional banking. USDT can also be beneficial for traders who wish to transfer funds between exchanges or take profits without banks.
