But what exactly is Tether (USDT), how does this stablecoin work, and what advantages and disadvantages does it offer? In this guide, you'll learn everything about one of the most important cryptocurrencies in the market.
We’ll explain what USDT is, how it functions, and explore its alternatives.
What Is USDT (Tether)?
USDT, also known as Tether, is a stablecoin pegged to the value of the US dollar. Unlike Bitcoin or Ethereum, whose prices can fluctuate significantly, USDT aims to maintain a stable value of approximately $1. Each USDT token is theoretically backed by an equivalent amount of dollars or other assets.
Tether was designed to combine the benefits of cryptocurrencies with the stability of traditional fiat currencies. As a token existing across multiple blockchains, USDT enables fast and low-cost transactions while maintaining a stable value—at least in theory.
The concept behind Tether is simple: For every USDT token issued, one US dollar should be held in reserve. This 1:1 peg to the dollar aims to shield the stablecoin from the extreme volatility seen in cryptocurrencies like Bitcoin.
Who Created Tether and Why?
Tether’s history began in November 2014 when the project was originally launched under the name "Realcoin" by Brock Pierce, Reeve Collins, and Craig Sellars. Shortly after its inception, it was rebranded as "Tether." The company behind it, Tether Limited, has close ties to the crypto exchange Bitfinex, which has sparked controversies in the past.
The primary purpose of Tether was to bridge conventional fiat currencies and cryptocurrencies. Before USDT, traders often struggled to quickly switch between volatile crypto assets and stable fiat currencies. With USDT, users can hold their funds in a stable digital form without leaving the crypto ecosystem.
Since its launch, Tether has become the leading stablecoin and one of the largest cryptocurrencies by market capitalization globally, demonstrating the high demand for stability in the crypto market.
How Does USDT Work?
USDT operates on a relatively simple principle: For every Tether token issued, Tether Limited theoretically holds a corresponding amount of reserve assets. These reserves are primarily composed of US dollars but may also include other assets like bonds or loans.
Unlike Bitcoin, Tether doesn’t have its own blockchain but leverages existing networks. USDT was initially built on the Bitcoin blockchain protocol but is now available across multiple networks:
- Ethereum (ETH): Most USDT supply runs as ERC-20 tokens on Ethereum.
- Tron: A significant portion is traded on the Tron network.
- Other supported blockchains include Solana, Algorand, and Avalanche.
This versatility allows users to choose the network that best suits their needs in terms of speed, fees, and compatibility.
When a user wants to buy USDT, they theoretically deposit US dollars with Tether Limited, which then issues new USDT tokens. Conversely, users can redeem USDT tokens for USD. In practice, this exchange primarily happens through crypto exchanges where USDT is traded against other currencies.
Pros and Cons of USDT
Advantages
- Stability: The most obvious benefit of USDT is its price stability compared to volatile cryptocurrencies like Bitcoin. Its peg to the US dollar makes it a safe option during market turbulence.
- Liquidity: Tether is among the most liquid cryptocurrencies, meaning it can be bought and sold quickly—a crucial advantage for traders.
- Accessibility: USDT is available on most major crypto exchanges and can be traded seamlessly.
- Fast Transactions: Depending on the blockchain network, USDT transactions can settle in minutes—much faster than traditional bank transfers.
- Low Fees: Transaction costs for USDT are often lower than traditional banking fees, especially for cross-border transfers.
Disadvantages
- Centralization: Unlike decentralized cryptocurrencies like Bitcoin, USDT is controlled by a single company, contradicting crypto’s decentralized ethos.
- Reserve Controversies: There have been repeated doubts about whether Tether Limited holds sufficient reserves. While the company has published audits, critics argue transparency remains incomplete.
- Regulatory Risks: As a stablecoin, USDT faces scrutiny from regulators, potentially leading to sudden policy changes.
- Dependence on Tether Limited: USDT’s value relies on trust in the company. Financial instability could jeopardize the stablecoin’s peg.
The Current USDT Price
USDT’s price should theoretically stay close to $1 due to its dollar peg. However, minor fluctuations (within a few cents) can occur.
Historically, there have been moments when USDT’s price deviated more noticeably. The most notable instance was in October 2018 when its value briefly dropped to ~$0.85, raising concerns about Tether’s reserves. Since then, the price has stabilized near the 1:1 ratio.
USDT’s price is primarily determined by user trust in Tether Limited. As long as investors believe the company holds sufficient reserves, the peg remains stable.
USDT vs. Bitcoin: Key Differences
Tether and Bitcoin are fundamentally different cryptocurrencies:
- Purpose: Bitcoin is a decentralized alternative to fiat, while USDT is a stable digital dollar equivalent.
- Volatility: Bitcoin’s price swings make it speculative; USDT aims for stability.
- Technology: Bitcoin has its own Proof-of-Work blockchain; USDT uses existing networks.
- Supply: Bitcoin has a fixed cap of 21 million coins; USDT’s supply adjusts to demand.
- Decentralization: Bitcoin is fully decentralized; USDT is centrally managed.
- Use Case: Bitcoin is "digital gold"; USDT is a trading medium.
How to Buy and Use USDT
Buying USDT is straightforward:
- Crypto Exchanges: Purchase USDT with fiat or other cryptos on platforms like Binance or Coinbase.
- Peer-to-Peer (P2P): Buy directly from sellers on P2P marketplaces.
- Crypto Swaps: Exchange Bitcoin or Ethereum for USDT.
After purchasing, you can:
- Trade other cryptocurrencies.
- Transfer value quickly.
- Store USDT in wallets (ensure network compatibility).
- Use in DeFi for lending or yield farming.
Always follow security best practices: safeguard private keys and verify transaction details.
Conclusion
USDT (Tether) plays a vital role as the leading stablecoin, offering stability for traders and a safe haven in volatile markets. However, its centralized nature and reserve controversies warrant caution.
While USDT excels for trading and transfers, Bitcoin remains superior as a long-term, decentralized store of value.
