Tether (USDT) is one of the most widely used stablecoins in the cryptocurrency ecosystem. Designed to maintain a 1:1 value peg with the U.S. dollar, USDT offers traders and investors a reliable digital asset that combines the stability of fiat currency with the speed and flexibility of blockchain technology. Over recent years, its trading volume and liquidity have surged, solidifying its position as a cornerstone of crypto markets.
Like other stablecoins, USDT plays a vital role in cryptocurrency trading by allowing users to hedge against market volatility—especially during turbulent swings in Bitcoin and other digital assets. It eliminates the delays and fees associated with converting between crypto and traditional fiat currencies, making it an essential tool for active traders and long-term holders alike.
The Role of Tether in the Crypto Ecosystem
As of late 2020, Tether ranked as the fourth-largest cryptocurrency by market capitalization—surpassed only by Bitcoin, Ethereum, and XRP—with a valuation nearing $20 billion. More notably, Tether consistently leads in daily trading volume, often exceeding even Bitcoin’s turnover. This dominance highlights its widespread adoption across exchanges and platforms worldwide.

Tether was originally launched in 2014 under the name Realcoin by Bitcoin investor Brock Pierce, entrepreneur Reeve Collins, and software developer Craig Sellers. It began as a token on the Bitcoin blockchain via the Omni Layer protocol. However, as demand grew, Tether expanded to multiple blockchains, including Ethereum (as an ERC-20 token), TRON (TRC-20), EOS, Algorand, Solana, and others.
Today, the majority of USDT supply exists on the Ethereum network as ERC-20 tokens. This multi-chain presence enhances accessibility and reduces transaction costs depending on network congestion and user preferences.
How Does Tether Maintain Its Value?
At its core, Tether's appeal lies in its price stability—anchored directly to the U.S. dollar. Each USDT token is theoretically backed by one U.S. dollar held in reserve by Tether Limited, a Hong Kong-based company. While initially backed solely by cash reserves, Tether now includes other assets such as cash equivalents, treasury bills, secured loans, and corporate bonds.
Every issued and circulating Tether unit is backed 1:1 by equivalent fiat currency reserves held by Tether Limited.
Despite occasional short-term fluctuations—such as briefly reaching $1.20 in early years—USDT has maintained remarkable price stability since 2019. This consistency stems from growing trading volumes, improved market infrastructure, and increased transparency efforts by the issuer.

Practical Uses of USDT
Hedging Against Market Volatility
When Bitcoin or other cryptocurrencies experience sharp price drops, traders can quickly convert their holdings into USDT to preserve value without exiting to fiat. This allows them to stay within the crypto ecosystem while avoiding downside risk.
Seamless Exchange-to-Exchange Transfers
Moving funds between exchanges can be slow and expensive when using bank transfers. With USDT, users can transfer value almost instantly across platforms—especially useful for arbitrage strategies where timing is critical.

Trading on Crypto-Only Exchanges
Some exchanges do not support direct fiat deposits or withdrawals but offer robust trading pairs with USDT. This enables global users to trade cryptocurrencies efficiently—even in regions with limited banking integration—without exposing themselves to additional volatility from using BTC or ETH as base pairs.
Forex-Style Trading Strategies
Because USDT mirrors the USD, it serves as a digital proxy for dollar-based foreign exchange trades. Traders can exchange local currencies into USDT when their domestic currency is strong and later convert back when it weakens—effectively executing forex-like strategies within the crypto space.
Storing and Managing USDT Safely
USDT can be stored in various cryptocurrency wallets, including:
- Web and Mobile Wallets: Such as Trust Wallet
- Hardware Wallets: Like Ledger (supports ERC-20 USDT only)
- Exchange Wallets: Binance, OKX, and others
However, caution is crucial due to Tether’s presence on multiple blockchains. When sending or receiving USDT, you must ensure both sender and receiver use the same network (e.g., ERC-20, TRC-20, BEP-20). Sending USDT via the wrong chain—such as depositing Omni USDT to an ERC-20 address—can result in permanent loss of funds.
As of December 2020, Ledger hardware wallets only support ERC-20 USDT, meaning users cannot store Omni-based USDT on these devices.
Other Tether Variants
Beyond USDT, Tether Ltd. has issued several other stablecoins pegged to different assets:
- EURT: Pegged to the Euro
- CNHT: Pegged to the Chinese Yuan (CNY)
- XAUT: Backed by physical gold
These tokens expand Tether’s utility beyond dollar-denominated transactions, catering to international markets and alternative investment strategies. Real-time issuance data for all Tether tokens is publicly available at Tether’s Transparency page.
Addressing Controversies and Trust
Tether has faced scrutiny over the years regarding the composition and auditability of its reserves. Questions about whether every USDT is fully backed have sparked debate among regulators and analysts. However, regular attestation reports and increasing transparency measures have helped maintain market confidence.
Despite controversies, Tether remains a dominant force in crypto due to its unmatched liquidity and integration across thousands of platforms. Still, users may consider alternatives like USDC, BUSD, TUSD, or PAX for additional diversification or regulatory comfort.
