Tether (USDT) is one of the most widely used digital assets in the cryptocurrency ecosystem. As a stablecoin pegged 1:1 to the U.S. dollar, it serves as a crucial bridge between traditional finance and the decentralized world of blockchain. With a market capitalization exceeding $170 billion, USDT ranks among the top cryptocurrencies by market cap and dominates trading volume across global exchanges.
But despite its widespread adoption, USDT has long been surrounded by controversy — from transparency concerns to regulatory scrutiny. In this comprehensive guide, we’ll explore what Tether really is, how it works, its underlying risks, and why it remains a cornerstone of crypto markets today.

How Does Tether (USDT) Work?
Tether is issued by Tether Limited, a company that claims each USDT token is backed by one U.S. dollar held in reserve. This means that for every USDT in circulation, there should be an equivalent amount of fiat currency or cash-equivalent assets stored in bank accounts.
The mechanism is simple:
- When users deposit U.S. dollars into Tether’s bank accounts, the company issues new USDT tokens.
- When users redeem their USDT, Tether burns the tokens and returns the corresponding fiat amount.
This 1:1 backing model aims to maintain price stability, making USDT ideal for traders seeking to avoid the extreme volatility of assets like Bitcoin or Ethereum.
However, unlike decentralized cryptocurrencies such as Bitcoin or Ethereum, USDT is centrally controlled. Tether Limited manages issuance, redemptions, and reserves — which introduces counterparty risk.
The Evolution of USDT Across Blockchains
Initially launched in 2015 on the Bitcoin network via the Omni Layer protocol, USDT was later expanded to support faster and more scalable blockchains:
- USDT-Omni: The original version, built on Bitcoin. Slow and expensive to transfer due to Bitcoin’s limitations.
- USDT-ERC20: Launched on Ethereum, offering faster transactions and broader DeFi integration.
- USDT-TRC20: Built on the Tron network, known for ultra-low fees and high throughput.
While these versions represent the same value (1 USDT = $1), they are not interoperable. Sending USDT-Omni to an ERC20 address, for example, could result in permanent loss of funds. Exchanges typically handle this by automatically detecting deposit types, but users must be cautious when withdrawing.

Why Is USDT So Dominant in Crypto Markets?
Before stablecoins like USDT emerged, traders had to convert fiat directly into Bitcoin or other cryptocurrencies — a process often hindered by banking restrictions, slow transfers, and regulatory hurdles.
USDT changed that dynamic by offering:
- Price stability: A reliable store of value during market swings.
- Global accessibility: No need for bank accounts; anyone with internet can use USDT.
- Seamless trading pairs: Most altcoins trade against USDT rather than USD or BTC.
During the 2017 crypto bull run, demand for fast and frictionless trading surged. At the same time, Chinese exchanges faced shutdowns of RMB deposit channels. USDT became the de facto on-ramp for Chinese investors — fueling its explosive growth.
Even today, over 70% of cryptocurrency trading volume involves USDT pairs, cementing its role as the backbone of digital asset markets.

Major Risks Associated With USDT
Despite its utility, USDT carries significant risks that users should understand.
1. Lack of Transparency
For years, Tether faced criticism over whether it actually held sufficient dollar reserves. Independent audits were long absent, leading to widespread skepticism.
In 2021, Tether finally released a reserve breakdown — revealing that only a portion of its backing was in actual cash, with large allocations in commercial paper and other less liquid assets. While improvements have been made since then, full real-time transparency remains elusive.
2. Regulatory Vulnerability
In April 2019, the New York Attorney General accused Tether and Bitfinex of covering up an $850 million loss through misleading claims about reserves. Bank accounts linked to Tether were frozen, triggering a temporary drop in USDT’s price — falling below $0.94 amid panic selling.
Although the situation stabilized after Bitfinex raised funds through a token sale (LEO), confidence in Tether took a hit.
3. Centralization Risk
Because Tether Limited controls issuance and reserves, users must trust the company won’t:
- Freeze individual wallets
- Halt redemptions during crises
- Mismanage or lose reserve funds
There is no guarantee that redemption will always be possible — especially under financial stress or legal pressure.
Frequently Asked Questions (FAQ)
Q: Is USDT really backed 1:1 by U.S. dollars?
A: Tether claims it is fully backed by reserves including cash, cash equivalents, and short-term deposits. However, only part of the reserve is held as actual cash — the rest consists of other assets like commercial paper.
Q: Can I lose money using USDT?
A: While USDT aims to maintain a $1 value, it can temporarily depeg during market stress. Additionally, sending it to the wrong blockchain network may result in irreversible loss.
Q: What happens if Tether goes bankrupt?
A: Holders could face partial or total loss of value if reserves are insufficient or frozen. Unlike bank deposits, USDT is not insured by institutions like the FDIC.
Q: Are there safer alternatives to USDT?
A: Yes — alternatives like USD Coin (USDC) offer greater transparency and regulatory compliance. However, they may come with stricter access controls.
Q: Can governments ban USDT?
A: Yes. Several countries have restricted or banned stablecoins due to concerns over capital controls and financial sovereignty.
Q: How do I redeem USDT for real dollars?
A: Direct redemption is limited to institutional clients. Most retail users exchange USDT through cryptocurrency exchanges.
