USDT, also known as Tether, is a type of cryptocurrency called a stablecoin. It was launched in 2014 by Tether Limited, a company based in Hong Kong. Unlike volatile cryptocurrencies like Bitcoin, USDT is designed to maintain a stable value by being pegged to the US dollar at a 1:1 ratio, meaning each USDT is intended to be worth about $1 USD at all times. This stability is achieved through reserves held by Tether, which are supposed to back the tokens with equivalent assets, such as cash, cash equivalents, and other financial instruments. USDT operates on multiple blockchains, including Ethereum, Tron, and others, making it widely used for trading, remittances, and as a bridge between fiat currencies and other cryptos. It’s one of the most popular stablecoins, with a market cap often exceeding $100 billion, but it has faced scrutiny over its reserve transparency and backing.
Below are the primary uses of USDT, based on its role in the crypto ecosystem:
Hedging Against Volatility: USDT serves as a safe haven for crypto traders and investors during market downturns. Its stable value allows users to park their funds in USDT without exiting to fiat currency, avoiding transaction fees and potential tax implications. For example, a trader can convert Bitcoin or Ethereum to USDT to lock in profits during a market dip without cashing out to USD.

Trading and Liquidity: USDT is the largest cryptocurrency by trading volume, accounting for roughly 70% of the stablecoin market share. It’s used as a base currency in trading pairs (e.g., BTC/USDT, ETH/USDT) on major exchanges like Binance, Kraken, and Coinbase, enabling seamless transitions between cryptocurrencies without fiat conversion. Its high liquidity ensures minimal price slippage, making it ideal for traders.
Cross-Border Transactions and Remittances: USDT facilitates fast, low-cost transfers across blockchains like Ethereum, Tron, and Solana, bypassing traditional financial intermediaries like banks. This makes it popular for international payments and remittances, especially in regions with limited banking access, as it combines the stability of the USD with the speed of crypto
Decentralized Finance (DeFi): USDT is widely used in DeFi protocols for lending, borrowing, and staking. Platforms like EarnPark leverage USDT in liquidity pools, offering up to 35% annual percentage yield (APY) through trading fees and compound interest. Users can stake USDT in DeFi to earn passive income while maintaining stability.
Payments for Goods and Services: USDT is increasingly accepted for real-world transactions. Major brands like Overstock and Expedia, as well as over 90 million merchants via crypto debit cards (e.g., Ledger’s CL Card), allow payments with USDT. It’s used for online shopping, software purchases, and even in-store transactions in supported regions like the UK and EEA.
Key Features Supporting Usage:
Multi-Blockchain Support: USDT operates on multiple blockchains, including Ethereum (ERC-20), Tron (TRC-20), Solana, and others, offering flexibility in transaction speed and cost. Tron dominates on-chain USDT usage with over $12 billion in 24-hour transfer volume as of early 2023.
Reserve System: Tether Limited claims USDT is backed 1:1 by reserves, including 84.58% in cash, U.S. Treasury bills, and other assets as of March 2024. However, transparency concerns and lack of full audits have sparked controversy, with critics questioning the reserve’s composition.
Accessibility: USDT is available on nearly all major crypto exchanges and can be stored in hot or cold wallets, such as Ledger Flex, ensuring secure and versatile management.
Risks and Considerations:
Regulatory Scrutiny: Tether has faced fines (e.g., $41 million by the CFTC in 2021) and allegations of market manipulation, raising concerns about its reserve backing.
Peg Stability: While designed to maintain a $1 value, USDT briefly dipped to $0.96 in May 2022 during market turmoil, highlighting potential vulnerabilities.
Regional Restrictions: As of 2025, USDT is being phased out in the EU due to non-compliance with regulations, pushing users toward alternatives like USDC.
How to Use USDT to Make Money
USDT’s primary appeal is its stability, which makes it less risky for holding value compared to other cryptos, but it also limits direct price appreciation. People use it in various strategies to generate returns, often through interest, lending, or trading ecosystems. Here’s a high-level overview of common approaches—note that all involve risks like platform failures, regulatory changes, or market volatility, and cryptocurrency activities can result in losses. Always research thoroughly and consider consulting financial advisors.
Lending and Earning Interest: Deposit USDT into platforms or exchanges that offer savings accounts or lending services, where you can earn annual percentage yields (APY) through interest paid by borrowers. Rates vary but have been reported up to 12-20% in some cases, compounded over time
This is passive but depends on the platform’s reliability.
Staking and Yield Farming: Lock USDT in decentralized finance (DeFi) protocols for rewards. For example, provide liquidity in pools (like USDT paired with another stablecoin) on platforms, earning fees from trades or additional tokens. Yields can fluctuate based on market conditions.
Trading and Arbitrage: Use USDT as a base in crypto trading pairs on exchanges to buy low and sell high on other assets, or exploit small price differences across platforms (arbitrage). Since USDT is stable, it’s often used to “park” funds during market dips.
Other Passive Methods: Some platforms offer cloud mining or ad-based earning tied to USDT, where you complete tasks or hold assets for daily payouts, though these can be low-yield or risky due to potential scams.
Centralized exchanges also provide earn programs for holding USDT.
These methods require a crypto wallet, exchange account, and understanding of fees, taxes, and security. Start small, as the crypto space is unregulated in many areas and prone to hacks or collapses.
Ethics and Norms
USDT has been a staple in crypto since its inception, normalizing stablecoins as tools for value transfer and trading without fiat conversions. However, it’s mired in ethical controversies that question its integrity and broader impact on the financial system. Norms in the crypto community emphasize transparency, decentralization, and risk awareness, but USDT often falls short, leading to debates about its responsible use.
Key ethical issues include:
Reserve Backing and Transparency: Tether has repeatedly claimed full 1:1 USD backing, but investigations revealed this wasn’t always true—e.g., at one point, only 27.6% was backed by cash, with the rest in riskier assets like commercial paper. The company was fined $41 million by the U.S. Commodity Futures Trading Commission in 2021 for misleading statements, and New York’s Attorney General banned it from operating in the state after finding false claims. Lack of independent audits raises concerns about potential fraud or insolvency, similar to FTX’s collapse.
Illicit Use and Regulatory Scrutiny: USDT’s pseudonymity and global reach make it attractive for money laundering, sanctions evasion, and criminal activities, including by terrorists or underground networks. U.S. authorities are investigating Tether for possible violations of anti-money laundering laws and sanctions, as reported in 2024. This has ethical implications for users: supporting USDT might indirectly enable harmful activities, though Tether denies wrongdoing and claims to freeze illicit funds.
Market Manipulation and Systemic Risk: Critics argue Tether’s issuance of billions in USDT without clear backing has artificially inflated crypto markets, potentially manipulating prices. With over $118 billion in circulation, a de-peg or failure could cause widespread panic, affecting innocent investors—echoing systemic risks in traditional finance.
On the positive side, Tether defends its practices, emphasizing utility for underserved regions and compliance efforts. Norms suggest diversifying to more transparent alternatives like USDC, which undergoes regular audits. Ethically, using USDT is a personal choice: it’s convenient and widely accepted, but prioritizing it over regulated options could perpetuate opacity in crypto. Many in the community view it as a necessary evil, but substantiated claims of misconduct make it a red flag for principled investors.
Conclusion:
USDT’s primary appeal lies in its stability, liquidity, and versatility, making it a cornerstone of crypto trading, DeFi, and cross-border payments. However, its centralized nature and transparency issues warrant caution. For beginners, USDT is a practical entry point to crypto, but users should research exchanges and wallets carefully and stay informed about regulatory developments.
