Tether (USDT) is one of the most widely used stablecoins in the cryptocurrency ecosystem. Designed to maintain a stable value by being pegged to traditional fiat currencies—primarily the U.S. dollar—USDT plays a critical role in digital asset trading, cross-border transactions, and portfolio stability. This guide explores what Tether is, how it works, its security, where to buy it, and practical use cases—especially for users in Latin America.
Understanding Tether (USDT)
Tether (USDT) was launched in 2014 through a collaboration between Bitfinex and Tether Limited. As a blockchain-based token, USDT is designed to mirror the value of the U.S. dollar on a 1:1 basis. Unlike volatile cryptocurrencies such as Bitcoin or Ethereum, USDT aims to eliminate price fluctuations, making it ideal for traders and investors seeking stability.
The core idea behind Tether was to solve two major issues in early crypto markets: high volatility and limited fiat currency convertibility. By anchoring its value to the U.S. dollar, USDT offers a reliable medium of exchange within decentralized networks.

What Is the Value of One USDT?
One USDT is designed to be worth exactly one U.S. dollar. While minor deviations can occur due to market dynamics, arbitrage mechanisms typically bring the price back in line with the dollar. This stability makes USDT a preferred choice for transferring value across exchanges without exposure to crypto market swings.
Is USDT Safe?
Tether claims that each USDT token is backed by reserves equivalent to one U.S. dollar. However, transparency has been a topic of debate. As of recent disclosures, only about 84% of Tether’s reserves consist of cash and cash equivalents. The remainder includes corporate bonds, secured loans, and other investments.
While this structure allows Tether Limited to generate returns on its reserves, it also introduces counterparty and liquidity risks—especially in light of past stablecoin failures like TerraUSD (UST). Regulatory scrutiny continues to grow, making it essential for users to understand that USDT is not insured or guaranteed by any government entity.
Key Differences Between USD and USDT
The U.S. dollar (USD) is a government-issued fiat currency recognized globally as legal tender. In contrast, USDT is a digital token operating on various blockchains (like Ethereum, Tron, and Solana) and is not legal tender in any country.
An important consideration: most exchanges do not guarantee redemption of USDT for actual dollars. Once you purchase USDT, you’re typically limited to using it within the crypto ecosystem—trading for other cryptocurrencies or transferring between wallets. Converting back to fiat usually requires using a regulated exchange with withdrawal capabilities.
How Many USDT Are in Circulation?
As of now, over 67.79 billion USDT are in circulation. This supply adjusts based on market demand and Tether Limited’s issuance policies. Its widespread adoption makes USDT one of the most liquid digital assets in the world.
Who Controls Tether?
Tether Limited is the company responsible for issuing and managing the USDT token. It oversees reserve management, audits (conducted periodically by third parties), and the minting/burning of tokens based on deposits and withdrawals.
While Tether has improved transparency over time—publishing quarterly attestations of its reserves—critics argue that full regulatory compliance and independent auditing are still lacking compared to traditional financial institutions.
Where Can You Use USDT?
USDT is accepted across numerous platforms, including:
- Binance
- Kraken
- Huobi

These exchanges allow users to trade major cryptocurrencies against USDT pairs (e.g., BTC/USDT, ETH/USDT), providing liquidity and minimizing volatility during trades.
Beyond trading, USDT is increasingly used for:
- Cross-border remittances

- Earning interest via crypto lending platforms
- Paying for services on select merchant sites
What Can You Buy With USDT?
While direct purchases of goods and services with USDT remain limited, its utility lies in enabling access to the broader crypto economy. You can use USDT to buy:
- Bitcoin (BTC)
- Ethereum (ETH)
- Litecoin (LTC)
- Ripple (XRP)
- And hundreds of altcoins
Additionally, some online retailers and freelance platforms accept USDT through payment gateways integrated with crypto processors.

How to Store Your USDT Safely
Storing USDT securely is crucial. While many users keep their tokens on exchanges for convenience, this exposes them to platform-specific risks such as hacks or insolvency.
Safer storage options include:
- Web and mobile wallets: Trust Wallet, MetaMask (ensure compatibility with the network your USDT is on)
- Hardware wallets: Ledger or Trezor devices support multiple blockchain versions of USDT
Always verify the blockchain network when sending or receiving USDT (e.g., ERC-20, TRC-20, BEP-20). Transferring across incompatible networks may result in permanent loss of funds.
How to Buy and Sell USDT
Purchasing USDT is straightforward through cryptocurrency exchanges. Most platforms support buying with:
- U.S. dollars (via bank transfer, credit card, or wire)
- Other cryptocurrencies (BTC, ETH)
- Local payment methods (especially in Latin America)
Popular exchanges where you can buy USDT include:
- Coinbase
- eToro
- Binance
- Kraken
- Huobi
Selling USDT follows a similar process—you convert it back to fiat or another cryptocurrency depending on your needs.
How to Withdraw USDT to Your Bank Account
To convert USDT into real-world currency:
- Transfer your USDT to a regulated exchange that supports fiat withdrawals.
- Sell your USDT for USD (or your local currency).
- Withdraw the funds to your linked bank account.
Processing times vary by platform and region but typically take 1–5 business days.
