Tether (USDT) is a stablecoin pegged 1:1 to the US dollar, widely used in cryptocurrency trading as a stable bridge between fiat currencies and digital assets.
Backed by dollar-denominated reserves and issued across multiple blockchain protocols, it enables users worldwide to conduct fast, secure, and low-volatility value transfers.
Whether for depositing funds, transferring assets, or making payments, Tether has become a preferred tool for many crypto users.
Understanding Tether (USDT) and Its Background
Tether (USDT) is a blockchain-based cryptocurrency that originated on October 6, 2014. Initially launched as "Realcoin" to facilitate asset movement on the Bitcoin blockchain, it was rebranded as Tether (USDT) on November 20 of the same year by Tether Operations Limited.
Tether does not operate on its own native blockchain. Instead, it functions on various established blockchain networks, including Bitcoin, Ethereum, Avalanche, Polygon, Solana, and Tron. This multi-chain presence allows Tether to offer different functionalities depending on the underlying transmission protocol.
As of the latest data, the total market capitalization of Tether in circulation exceeds $93.7 billion, making it the third-largest cryptocurrency by market value, trailing only Bitcoin and Ethereum.
How Tether (USDT) Works
Tether is a dollar-pegged stablecoin and the world's largest by market capitalization. It maintains a 1:1 exchange rate with the US dollar, providing individuals, businesses, and institutions with a low-volatility entry and exit solution within cryptocurrency markets.
Tether’s price stability relies on its fully reserved asset backing. The company regularly updates and publishes audit reports to confirm that each issued USDT is backed by at least one US dollar or equivalent asset. Investors can redeem their USDT for actual US dollars from Tether Operations Limited at the 1:1 ratio.
The operational lifecycle of Tether involves five key steps:
- A verified user (individual, merchant, or institution) deposits fiat currency into Tether’s designated bank account.
- Tether issues the corresponding amount of USDT (minus applicable fees) and transfers it to the user’s wallet address.
- The user can freely trade, transfer, or hold USDT.
- If the user wishes to exit, they can deposit USDT back into their Tether account to convert it into fiat currency.
- Tether processes the redemption request, removes the USDT from circulation, and transfers the equivalent fiat amount to the user’s bank account.
Tether Operations Limited is the sole entity authorized to mint new USDT or remove it from circulation—a critical process for maintaining the system’s solvency.
For everyday users, this redemption mechanism is typically accessed through cryptocurrency exchanges rather than directly through Tether, which we will explore further in the purchasing section.
Why is Tether (USDT) Important?
As the leading stablecoin by market value, Tether plays a vital role in the crypto ecosystem. It serves as a bridge between traditional finance and the digital asset world, offering several essential functions beyond simply measuring the value of other cryptocurrencies.
≣ Pricing Unit for Crypto Assets
In the early days of crypto, traders often used Bitcoin or Ethereum as benchmark currencies for pricing other assets—a practice known as "coin-based valuation." The introduction of dollar-pegged stablecoins like Tether provided a more intuitive and globally recognized unit of account: the US dollar. This "dollar-based valuation" system simplifies trading and price evaluation.
≣ Digital Store of Value
Beyond USDT, Tether has expanded its offerings to include stablecoins pegged to other fiat currencies such as the Euro, Chinese Yuan, and Mexican Peso, as well as tokens backed by precious metals like gold. These digital alternatives provide a secure and portable means of storing value without the geographical and logistical limitations of physical assets.
≣ Medium for Everyday Transactions
A growing number of countries and businesses now accept cryptocurrency payments, with Bitcoin and Tether among the most widely supported. For instance, McDonald’s in Lugano, Switzerland, accepts Tether as payment, and numerous startups use USDT for payroll and vendor transactions.
Its stability and ease of transfer make Tether suitable for daily use in both personal and commercial contexts.

≣ Buying Tether (USDT) on International Exchanges
International exchanges often offer higher liquidity, a wider selection of cryptocurrencies, and more advanced trading tools. However, most do not support direct TWD withdrawals, making local exchanges a necessary gateway for Taiwanese users.
Binance, the world’s largest cryptocurrency exchange, supports multiple methods for acquiring USDT:
- Transfer USDT from another exchange or wallet.
- Use credit/debit cards, Apple Pay, or engage in peer-to-peer (C2C) trading.
To buy USDT via credit card on Binance:
- Open the Binance app and tap on "More" under the commonly used functions.
- Select "Buy Crypto," then choose USDT as the currency and enter the desired amount.
- Complete the purchase using Visa, Mastercard, or Apple Pay.
Note that buying USDT with a credit card typically incurs higher fees due to processing charges from both the exchange and the card issuer. Nonetheless, it remains one of the most convenient onboarding methods for new users.
