Tether, also known as $USDT, is a type of cryptocurrency called a stablecoin. It’s designed to match the value of the US dollar, giving you a digital asset that holds steady at $1. This makes it a useful tool for transferring funds between platforms, trading digital assets, or hedging against market swings without having to exit cryptocurrency entirely.
Unlike Bitcoin or Ethereum, which can rise or fall sharply, Tether provides a way to stay in the market without riding out that volatility.
👉 Stablecoins are cryptocurrencies designed to maintain a fixed value, usually pegged to fiat currencies like the US dollar. They combine the speed of crypto with the stability of traditional money. Learn more: How to Invest in Stablecoins
#How Tether Maintains Its Dollar Peg
Tether launched in 2014 with a simple idea: create a digital asset that holds its value by being backed 1 to 1 with the US dollar. For every USDT in circulation, the issuer claims to hold an equivalent value in reserves. This structure is designed to keep USDT trading close to $1, even when other cryptocurrencies experience sharp swings.
When it began, the total supply of USDT was less than $1 million. It passed $1 billion by 2018. As of mid 2025, USDT has reached a market cap of around $156 billion, making it the most widely used stablecoin in the market. Its rise is driven by stability, deep liquidity, and low transaction costs.
Tether’s growth has outpaced early expectations. Its widespread adoption as a liquidity bridge between exchanges and trading pairs has helped solidify its role as the primary transactional stablecoin across crypto markets.
#Why Traders Use Tether for Transfers
Tether is often used because it allows fast, low-cost transfers between wallets, exchanges, and platforms. Traditional bank wires can take days and may come with high fees. In contrast, USDT transactions settle quickly and cost less, especially on blockchains like Tron or Solana.
Its centralized issuance also allows for more predictable performance compared to decentralized networks like Bitcoin, where transaction speed and fees can fluctuate with congestion. Since crypto trades 24 hours a day, USDT offers uninterrupted access to liquidity without relying on bank hours.
#Why Tether’s Dollar Backing Has Raised Questions
Tether has faced criticism from the start. While its peg to the US dollar is meant to offer stability and protect against market volatility, the way it maintains that peg has not always been clear. In 2019, one of Tether’s lawyers confirmed that each USDT was only 74% backed by cash or cash equivalents at the time.
This raised doubts about whether Tether could meet redemptions if enough users wanted to cash out. Some have since referred to it as a partial reserve stablecoin, meaning its reserves may not fully match its supply at all times.
Even so, traders continue to rely on USDT for speed, liquidity, and access. Unless it loses its dollar peg or suffers a major collapse in trust, USDT is likely to remain a key component of crypto trading activity.
#Who Owns and Operates Tether?
Tether is often viewed as a blockchain-based asset, but it operates very differently from decentralized cryptocurrencies like Bitcoin. It is issued and managed by a private company, which has faced criticism over the years for its limited transparency and close ties to the crypto exchange Bitfinex.
In 2018, academic researchers examined Tether’s role during the 2017 crypto rally. Their findings suggested that Tether’s distribution was heavily concentrated, with most trading activity linked to a single large entity rather than broad market demand. Much of this activity flowed through Bitfinex, a major exchange based in Hong Kong, which was also linked to Tether’s creation and control.
These connections eventually led to a legal case brought by the New York Attorney General. The case accused Bitfinex of using Tether’s reserves to cover an $850 million loss. While the company settled without admitting wrongdoing, the case raised questions about governance, reserve integrity, and the relationship between the two entities.
Legal Settlement and Transparency Requirements
The New York Attorney General accused Bitfinex and Tether of covering up an $850 million loss in customer funds by using Tether’s reserves to fill the gap. It also alleged that Tether overstated its claim that every USDT was fully backed by US dollars.
To settle the investigation, both companies agreed to pay $18.5 million, stop serving customers in New York, and submit quarterly transparency reports for at least two years. They did not admit or deny the findings, but the case highlighted serious concerns about how USDT was managed and marketed.
While the settlement helped reduce some uncertainty, it also reinforced the need for clearer oversight in the stablecoin market. It marked a turning point where regulators began paying closer attention to how stablecoins operate and what backs them.
#Why Tether Sees Heavy Use in Asia
Tether has consistently seen high trading volumes in parts of Asia, particularly in regions with capital controls or limited access to regulated crypto markets. In countries like China, where direct Bitcoin trading is restricted, USDT often acts as a workaround. Users convert local currency into USDT through informal channels, then use those tokens to access broader crypto markets or make cross-border transfers.
The appeal lies in the dollar peg. For users in volatile or restricted fiat systems, holding USDT offers a way to preserve value and access global markets without relying on the traditional banking system.
This demand is also tied to informal financial networks, often described as shadow banking. These are unregulated intermediaries that facilitate crypto trades, lending, or remittance services outside official channels. While not exclusive to Asia, this structure helps explain why USDT volume in the region remains consistently high compared to other stablecoins.
The result is a stablecoin that has become a key liquidity tool in both formal and informal economies.
#How Tether Sparked the Rise of Other Stablecoins
Stablecoins have become essential in crypto markets because they combine the utility of digital assets with the price stability of fiat currency. Traders use them to move in and out of positions quickly, manage risk, or hold value without exiting the crypto ecosystem entirely.
Tether was the first stablecoin to gain global traction. Since then, dozens of others have entered the market, each offering a different approach to reserve management, transparency, and use case.
Here are a few key examples:
USDC is issued by Circle and backed 1 to 1 with US dollars held in regulated financial institutions. It’s often used in DeFi and payments.
FDUSD is a newer entrant supported by Binance and issued by First Digital. It has gained traction following the phase-out of BUSD.
DAI is a crypto-backed stablecoin governed by MakerDAO. It uses overcollateralized assets like Ethereum to maintain its peg to the US dollar.
TUSD and PAX are also fiat-backed and were once widely used on major exchanges, although usage has shifted over time.
PAXG is backed by physical gold and offers exposure to the gold price through a digital token.
Facebook’s stablecoin project, originally launched as Libra and later rebranded as Diem, was eventually shut down. This highlighted the regulatory hurdles faced by corporate-issued stablecoins and created more space for compliant alternatives to gain market share.
While most stablecoins are pegged to the US dollar, others are linked to assets like gold or issued by decentralized protocols. Each has different trade-offs in terms of security, governance, and stability.
The growing number of options reflects how central stablecoins have become to crypto infrastructure, enabling everything from everyday payments to high-frequency trading and collateralized lending.
#Why Some Investors Still Back Tether
Tether continues to hold its ground as the most used stablecoin in crypto. Despite years of legal scrutiny and questions about its reserves, it remains the primary tool for trading, transferring, and parking funds across crypto markets.
One reason for this is practicality. Unlike Bitcoin, which can swing in price over short periods, USDT offers price stability, instant settlement, and broad exchange support. For traders, it’s a reliable tool to manage risk and move capital without converting back to fiat.
Institutional participation has also helped. Over the past few years, crypto adoption has expanded beyond retail investors. Trading desks, hedge funds, and payment platforms now rely on stablecoins like USDT to handle liquidity, cross-border transactions, and settlement. This demand has helped Tether scale, even as other projects have faded or been delisted.
As regulation matures in the US, Canada, and Europe, stablecoins are starting to play a formal role in financial markets. If Tether can maintain its peg and improve transparency, it is likely to remain a core player.
#What Could Limit Tether’s Growth
Even with strong usage, Tether faces pressure on multiple fronts. Its base of operations is offshore, and that limits its access to regulated financial systems in places like the US and the EU. For example, Tether has been delisted from some European exchanges due to non-compliance with new licensing rules.
There is also competition. USDC and FDUSD are gaining ground thanks to clearer regulatory status and closer ties to traditional financial institutions. If central banks roll out digital currencies at scale, the role of privately issued stablecoins could shift.
Tether has managed to keep its peg and scale its reserves, but it still operates with less transparency than some of its peers. That may be acceptable for traders who prioritize speed and liquidity, but institutional users may prefer alternatives with more regulatory backing.
Tether is not positioned to replace Bitcoin as a store of value, but it plays a different role. Its strength lies in liquidity, trading utility, and dollar exposure. Whether it retains that lead will depend on how it responds to new regulation, growing competition, and rising expectations from institutional users.
