What Is USDT and How Does It Work?
Tether (USDT) is a type of cryptocurrency known as a stablecoin. It is designed to maintain a stable value by being pegged to a fiat currency—in this case, the US dollar. The idea is simple: for every USDT in circulation, there should be one US dollar held in reserve by the issuing company, Tether.
Tether Limited, the company behind USDT, is part of the iFinex ecosystem, which also includes the Bitfinex cryptocurrency exchange. As a fiat-collateralized stablecoin, USDT relies on the promise that users can redeem their tokens for actual US dollars at a 1:1 ratio.
With a market capitalization in the tens of billions, USDT is the most widely used stablecoin. It serves as a fundamental settlement currency for a vast number of cryptocurrency trades and over-the-counter (OTC) transactions globally.
Why Is USDT So Controversial?
The primary concern surrounding USDT is whether Tether actually holds sufficient dollar reserves to back all the USDT in circulation. These doubts have persisted for years.
USDT's circulating supply saw explosive growth starting in 2017. While some speculated that Tether was "printing" USDT to artificially inflate the price of Bitcoin, others argued that the growth was a natural result of rising demand in the crypto market.
A significant moment in the controversy arrived in 2019. The New York Attorney General (NYAG) filed a lawsuit against Bitfinex, alleging that the exchange had covered up an $850 million loss by borrowing funds from Tether's reserves.
This incident revealed that Tether's reserves were not fully backed at that time. The company admitted that only about 74% of USDT was backed by cash and equivalents. Furthermore, Tether quietly changed its terms of service, no longer guaranteeing that each USDT was backed solely by a US dollar, but instead by a basket of assets that could include loans to affiliated companies.

The Legal Battle and Its Implications
The NYAG's case centered on the alleged co-mingling of funds between Bitfinex and Tether. The dispute began when Bitfinex's payment processor, Crypto Capital, had its funds frozen by authorities. To cover the shortfall, Bitfinex obtained a loan from Tether.
This event shook market confidence. The lawsuit is ongoing, with both companies having submitted millions of pages of documents for review. The case has brought unprecedented scrutiny to Tether's operations and reserve claims.
In response to the allegations and to reassure the market, Tether has since claimed that its stablecoin is once again 100% backed, though the composition of these reserves has changed to include a variety of assets beyond just cash.
Can You Really Redeem 1 USDT for 1 USD?
This is the million-dollar question for many investors. The theoretical promise of stablecoins is their redeemability.
Despite the controversies, major players in the crypto industry assert that redemption is functioning. For instance, Sam Bankman-Fried, the former CEO of FTX, publicly stated that the idea that USDT couldn't be redeemed was "funny," noting that his exchange redeemed large sums regularly.
The redemption process is typically not designed for individual retail users directly through Tether. Instead, it is large entities like cryptocurrency exchanges and OTC desks that handle the bulk of conversions, buying and selling USDT in massive volumes to provide liquidity for their users.
For the average person, the most common way to "cash out" USDT is through a trusted exchange or OTC platform that offers a USDT-to-USD trading pair, effectively achieving the same result as a direct redemption.
The Role of USDT in Global Finance
Beyond trading, USDT has found a significant niche in cross-border payments and as a tool for circumventing capital controls in certain countries. Its high liquidity and stability make it an attractive vehicle for moving value across borders without relying on traditional banking systems.
Reports suggest that enormous volumes of USDT are traded OTC in regions with strict capital controls. Businesses and individuals use it to transfer value internationally, later converting it into local currency through OTC brokers. This real-world utility is a key driver of USDT's sustained demand.
Frequently Asked Questions
Is USDT safe to use?
USDT is the most liquid and widely adopted stablecoin. While its history involves legal controversies and questions about its reserves, it remains a cornerstone of the crypto economy. For everyday trading and short-term holdings, it is generally considered functional. For long-term storage of large sums, some users prefer to diversify with other stablecoins or assets.
How can I convert USDT back to US dollars?
Most users convert USDT to USD through a cryptocurrency exchange. You would sell your USDT on the exchange's trading platform for USD and then withdraw that USD to your linked bank account. The process is similar to selling any other cryptocurrency.
What backs USDT now?
Tether states that USDT is backed 100% by reserves. However, these reserves are no longer exclusively cash. They include a variety of assets such as cash equivalents, commercial paper, and other investments. The exact composition is periodically disclosed in reports on Tether's website.
What was the outcome of the NYAG lawsuit?
The case was settled in 2021. Bitfinex and Tether did not admit to wrongdoing but agreed to pay an $18.5 million fine and to cease trading with New Yorkers. They also agreed to provide regular, public reports on the composition of their reserves for the next two years.
Are there alternatives to USDT?
Yes, there are several other reputable stablecoins. USD Coin (USDC) and Binance USD (BUSD) are two major alternatives that are often perceived as having more transparent and regular audits of their reserves.
Why does Tether not have a full, real-time audit?
Tether has stated that providing a continuous, real-time audit is complex due to the structure of its reserves and the need to protect commercial relationships and customer privacy. It instead provides quarterly attestations that detail the breakdown of its holdings.
Conclusion
The debate around Tether's reserves is a crucial one for the crypto industry. While past events rightly raised concerns, the current evidence suggests that USDT can be redeemed for dollars through established market channels. Its unparalleled liquidity and entrenched position in the crypto ecosystem make it a tool that exchanges and large traders have a vested interest in maintaining.
The market itself acts as a continuous audit. If USDT were significantly under-collateralized, it would likely trade below its $1.00 peg, which, despite occasional minor deviations, it has largely maintained. For users, understanding both the utility and the history of USDT is key to making informed decisions in the digital asset space.
