What Is USDT (Tether)
USDT (Tether) is the largest and most popular stablecoin that aims to keep its price around $1 per token and works as a reliable “digital dollar” for trading, payments, and international transfers.
USDT was launched by Tether in 2014 and belongs to fiat-backed stablecoins: the current stablecoin price is supported by the issuer’s real reserves — cash, bank deposits, and U.S. Treasury bills. Today, USDT operates on multiple networks (Ethereum, Tron, Solana, BNB Chain, and others) and consistently ranks in the global top 3 cryptocurrencies with a market cap of over $180 billion. Because of this, USDT has become the main tether crypto for the entire market: it powers liquidity for tens of thousands of trading pairs and supports millions of daily user operations.
Stablecoins are cryptocurrencies whose price is pegged to the value of traditional assets (most often fiat currencies like the dollar or euro) to reduce volatility and simplify transactions.

What Is USDT Used For
USDT is used to give users a digital alternative to the dollar inside the crypto world — a bridge between fiat money and digital assets. According to Tether, USDT is used by 500 million people worldwide, and below, we will take a closer look at what is usdt used for across different scenarios — from trading to payments and transfers.
1. What Is USDT Used For During Volatility?
The crypto market can rise +20% in a day and then instantly drop –30%. This is where it becomes clear what is usdt used for during volatility: when you see the market starting to fall sharply, you can move part of your assets into a stablecoin and lock in their current value. For example, you hold Bitcoin, notice the price going down, and simply swap BTC for USDT — the stablecoin price stays close to $1, and your funds stop depending on sudden market swings.
2. USDT Trading: Why Tether Is the Main Trading Pair in Crypto
USDT is widely used as a trading pair on cryptocurrency exchanges such as Hyperliquid, Uniswap, PancakeSwap, as well as on major centralized platforms like Binance or Bybit. According to CoinGecko, the average USDT trading volume in October 2025 was around $125–130 billion. Pairs like BTC/USDT, ETH/USDT, and SOL/USDT provide a significant share of the market’s liquidity: when you look at btc usdt price or eth usdt price, you see how much Bitcoin or Ethereum costs in digital dollars. Traders often convert assets into USDT to lock in profits without withdrawing funds into fiat.
3. What Is a USDT Transfer
A USDT transfer is the process of sending or receiving Tether between cryptocurrency wallets, including cross-border transactions that happen without banks, delays, or country restrictions.
For example, if you want to send money to your family for the holidays, you no longer need to visit a bank, wait for opening hours, or stand in line. With USDT, the transfer is almost instant: you make the transaction, and the recipient sees the funds in their balance just a couple of minutes later. USDT transfers also come with very low fees. In some networks like TRON, these fees can be reduced almost to zero thanks to TRX staking. You can learn more about this in our article “How to Stake TRON”.
USDT is especially helpful in countries with weak or unstable banking systems. People can send and receive money directly and also protect the value of their savings during periods of high inflation.
4. What Is a USDT Payment
A USDT payment is a way to send Tether from one digital wallet to another when you need to make any type of online purchase.
USDT payment is used for:
-
online shopping (Shopify)
-
paying for games and subscriptions (Xbox, Microsoft Store)
-
booking flights and hotels (Travala, Alternative Airlines)
-
buying digital products and gift cards (Amazon, Airbnb)
-
paying for VPNs and online services (Proton Mail)
-
topping up mobile phone plans
-
purchasing courses and online learning
-
paying for domains and hosting
5. Why USDT Is Used to Protect Funds
When the market begins to drop, USDT becomes a convenient way for investors to preserve capital. Instead of watching the value of Ethereum or BNB fall together with the market, part of the portfolio is converted into a stablecoin — this makes it easier to lock in results and maintain funds in the form of “digital dollars”. This is where you clearly see what is usdt used for in the context of savings: protecting your balance from heavy volatility and waiting for a comfortable entry point back into the market.
