The cryptocurrency markets are well-known for their sudden and wild price swings. This has led to speculators flocking to the market to gain exposure to the industry in the hope that they will be on the winning end of volatility. As a way to hedge against the volatility, stablecoins were introduced to the market which are tied to fiat currencies such as the US Dollar. This gives investors a familiar and reliable price point to investor and trade the asset class.
Stablecoins such as Tether (USDT) and USD Coin (USDC) are widely known and used on the most popular cryptocurrency exchanges, trading platforms and wallets as a stable "digital fiat currency". While Tether is the larger and more widely traded coin, questions surrounding its cash reserves and regulatory troubles have turned investors to USDC as it may be a safer stablecoin than USDT. This article will explore the history behind USDT and USDC, what the differences are between the two stablecoins and which is better to use for cryptocurrency trading.
What Is A Stablecoin?
Stablecoins are a group of cryptocurrencies that are worth the same as one United States dollar, within a minimal margin. There are other fiat currency stablecoins on the market, however, the USD-dominated coins are the most popular in terms of market capitalization. The objective of stablecoins is to provide a digital currency that has a stable and reliable price.
While there are subtle fluctuations in the price, stablecoins can be traded with minimal volatility using a familiar unit of account. Common use-cases for stablecoins include a store of value, trading between other cryptocurrencies and investment vehicles to earn interest on lending and borrowing platforms.
USDC vs. USDT: Overview
USD Coin, often referred to as USDC, is a United States dollar stablecoin created by Circle this is used for financial payments and trading. Circle is a global technology company that worked closely with cryptocurrency exchange Coinbase and Bitcoin mining firm Bitmain on the USDC project. USDC runs natively as an Ethereum ERC-20 token. There are also versions for the Algorand, Solana, Stellar, TRON, Hadera and Avalanche blockchains through the USDC smart contract.
As of this writing, there are 52.6 billion USDC in circulation, representing $52.6 billion in cryptocurrency. Circle states that USDC is fully backed by cash and cash equivalents, including U.S. Treasuries. USDC is audited by the public accounting firm Grant Thornton monthly, where they publish a report showing that the currency is fully backed by fiat currency and equivalent assets. According to CoinMarketCap, it is the fifth-largest cryptocurrency by market capitalization.
Tether is a popular stablecoin that is tied to a range of fiat currencies, including the United States dollar and physical gold. Newly minted USDT tokens are anchored to the US Dollar on a 1 to 1 basis and stored in the company's treasury. Tether is closely affiliated with Bitfinex which is a large cryptocurrency exchange. Tether coins are available on the Algorand, Ethereum, EOS, Liquid Network, Omni, Tron, Bitcoin Cash Standard Ledger Protocol, and Solana blockchains.
Tether was the first blockchain-enabled that used a stable form of accounting which was developed to solve the inherent problem of volatility in the cryptocurrency market and to facilitate blockchain-based transactions using a familiar unit of account. Since Tether was introduced to the market, it has become the most widely used stablecoin with a current market capitalization of $78.7 billion, which equates to the 3rd largest cryptocurrency in the world.
Tether issues new currency when it receives fiat equivalents and has one-to-one backing for each Tether issued. Accounting firm Moore releases regular reports confirming a mix of cash and equivalents, bonds, funds, precious metals, secured loans to non-affiliated entities, and other investments. However, according to the New York State Attorney General, Bitfinex and Tether have hidden losses and comingled funds inappropriately and were fined.
USDT vs USDC: Origins & Management
USDC and USDT both aim to give cryptocurrency investors and traders a stable currency that’s worth one dollar instead of the high volatility of traditional cryptos like Bitcoin and Ethereum. USD Coin was announced in May 2018 and launched in September of the same year. Tether was one of the earliest stablecoins, introduced in 2012 and launched in July 2014.
Tether is an independent company but maintains close ties to Bitfinex. That is part of what has driven the recent controversy with the same person is the CTO of both Bitfinex and Tether. Circle is also an independent company, though it maintains a close relationship with Coinbase. Coinbase goes as so far as to call it a “stablecoin by Coinbase.” However, it doesn’t have the same history of legal troubles and questions regarding its cash and asset reserves.
USDT vs USDC: Risks & Security
Stablecoins such as USDC and USDT are similar in that they are pegged 1:1 with fiat currency with reserves in cash and assets. Tether has had a history of questionable activity that has introduced risk in the market. In August 2021, Tether was quoted as stating that “Tether has always been fully backed.” However, in the same month, the New York State Attorney General Latisha James said, “Tether’s claims that its virtual currency was fully backed by U.S. dollars at all times was a lie.” In the end, Tether paid an $18 million fine and agreed not to conduct business in New York (didn’t admit any wrongdoing).
Tether has since released reports “proving” that it is fully backed but these incidents lead to questions on the stability and security of USDT. In contrast, USD Coin has not had any issues with providing transparency on its reserves to prove it holds sufficient assets to maintain the backing of the stablecoin. Therefore, USD Coin may be a better option for risk-averse investors as it does not have a history of legal complaints with regulators.
