Español (Argentina)- USDT (Tether) is a stablecoin designed to stay at $1.
- It is issued by Tether Limited and backed by reserves, mostly short-term US Treasury bills.
- The same USDT exists on many blockchains: Tron, Ethereum, BNB Chain, Solana, TON and others.
- It is the most popular coin for casino deposits because the value does not swing while you play.
What is USDT, in one paragraph
USDT, also called Tether, is a cryptocurrency built to be worth one US dollar. It is a stablecoin: instead of rising and falling like Bitcoin, it tracks the dollar. You can send it anywhere in the world in minutes, at any hour, without a bank. That makes it the "digital dollar" of the crypto world, and the most traded cryptocurrency by daily volume.
How Tether keeps its value at $1
Tether Limited issues new USDT when customers deposit dollars and destroys USDT when they redeem it. The company says each token is backed by reserves, mostly short-term US Treasury bills plus cash, and it publishes quarterly attestation reports on those reserves.
Market forces keep the price close to $1. If USDT trades at $0.99, traders buy it cheaply and redeem it for $1; if it trades above $1, they mint new tokens at $1 and sell them. The price can drift a little in times of panic, but it has stayed close to a dollar through most of its history.
USDT is a dollar substitute, not an investment. It is meant to hold its value, not to grow.
USDT networks: the same coin on different blockchains
USDT is not tied to one blockchain. Tether issues it on several networks, and each version only works on its own network. USDT on Tron (often called TRC-20) and USDT on Ethereum (ERC-20) are the same dollar, but you cannot send one to an address on the other network.
| Network | Token standard | Fees | Speed |
|---|---|---|---|
| Tron | TRC-20 | Low | Fast |
| Ethereum | ERC-20 | Higher | Medium |
| BNB Smart Chain | BEP-20 | Low | Fast |
| Solana | SPL | Very low | Very fast |
| TON | Jetton | Very low | Very fast |
Choosing the right one saves money and prevents lost transfers. We compare them in detail in which network is best for USDT.
Why people use USDT
- Stable value. $100 today is still about $100 tomorrow.
- Fast transfers. Minutes instead of days for international payments.
- Low fees on networks such as Tron, Solana and TON.
- 24/7 availability. No bank holidays or cut-off times.
- Liquidity. Almost every exchange and crypto casino accepts it.
Risks to know about
- Issuer risk. You rely on Tether Limited holding the reserves it reports.
- Freezing. Tether can freeze addresses linked to crime on request from authorities.
- Regulation. Rules for stablecoins differ by country and can change; in the EU, MiCA rules have led some exchanges to limit USDT trading.
- Human error. A wrong network or address can mean lost funds, and there is no bank to reverse it.
A short history of USDT
Tether launched in 2014, first as a token on top of the Bitcoin blockchain. It moved to Ethereum as that network grew, and later to Tron, where low fees made it the favourite for everyday transfers. Today the same dollar token is issued on many networks, and Tron and Ethereum together carry most of it.
Over the years Tether has faced questions about its reserves and has settled cases with US authorities over past statements about them. In response it began publishing regular reserve reports and shifted most reserves into short-term US Treasury bills. Its long record of holding close to $1 is the main reason markets trust it, but it remains a private company's promise, not a government guarantee.
USDT vs USDC: which stablecoin to use?
| USDT | USDC | |
|---|---|---|
| Issuer | Tether Limited | Circle |
| Backing | Mostly US Treasury bills, plus other assets | Cash and short-term US Treasuries |
| Reports | Quarterly attestations | Monthly attestations |
| Main networks | Tron, Ethereum and many others | Ethereum, Solana and many others |
| Where it is strongest | Asia, Latin America, crypto casinos and P2P | US and EU platforms, regulated services |
For casino use, both work the same way: one token is meant to be one dollar. USDT is accepted in more places and has the deepest liquidity on Tron; USDC is often preferred on regulated platforms in Europe. SpinCrypto accepts both, so pick the one your exchange and wallet handle best.
How to check a USDT transfer
Every USDT transfer is public on its blockchain. To see where yours is, copy the transaction hash from your wallet or exchange and paste it into the explorer for that network: Tronscan for Tron, Etherscan for Ethereum, BscScan for BNB Chain, Solscan for Solana or Tonviewer for TON. You will see the amount, the receiving address and the number of confirmations. If the explorer shows the transfer as confirmed to the right address, the funds have arrived and any delay is on the receiving side.
Practical tips for using USDT
- Keep a small amount of the network's own coin (TRX, ETH, BNB, SOL or TON) to pay fees.
- Check exchange withdrawal fees as well as network fees; exchanges often charge a flat amount per network.
- Use the same network from start to finish: buying, holding and depositing.
- Save frequently used addresses in your wallet's address book to avoid copy-paste errors.
- Treat any message offering to "double" your USDT or recover lost funds as a scam.
Common USDT mistakes and how to avoid them
| Mistake | How to avoid it |
|---|---|
| Sending on the wrong network | Pick the same network on both sides and check the address format (T… on Tron, 0x… on Ethereum and BNB Chain). |
| No coin for fees | Keep a little TRX, ETH, BNB, SOL or TON in the wallet that holds USDT. |
| Copying a look-alike address | Copy addresses from the source, not from your transaction history, and check the first and last characters. |
| Ignoring exchange fees | Compare the withdrawal fee for each network on your exchange before sending. |
| Buying from strangers | P2P deals outside a platform with escrow are a common way to lose money. |
Keep USDT on an exchange or in your own wallet?
Leaving USDT on an exchange is convenient for trading, but the exchange holds the keys and can freeze or limit withdrawals. Some exchanges also restrict transfers to gambling sites. A non-custodial wallet in between gives you control: buy on the exchange, send to your wallet, and from there to the casino. Winnings come back to the same wallet, under your control. Our wallet guide explains how to set one up safely.

Using USDT at an online casino
For casino players, USDT solves the main problem with crypto: volatility. If you deposit Bitcoin and its price drops 5% during your session, you lose money without placing a bet. With USDT, a $100 deposit stays worth $100. At SpinCrypto, USDT deposits start at $1 and withdrawals are processed within an hour; see our payments guide for the steps.
