USDT is Tether, the largest stablecoin by market capitalization and daily trading volume.
It is a digital token pegged to the US dollar, meaning 1 USDT is designed to always equal $1.
Unlike Bitcoin or Ethereum, whose prices fluctuate with the market, USDT holds a stable $1 value because Tether holds reserves backing each token in circulation.
You can use USDT to buy, sell, and settle crypto transactions without converting to or from fiat currency each time.
This guide explains how USDT works, how it compares to USDC, which network to use, and what stablecoin settlement means for anyone buying or selling large amounts of Bitcoin.
Key Takeaways
- USDT is a stablecoin pegged to the US dollar, issued by Tether. 1 USDT = $1, backed by Tether’s reserves.
- USDT runs on multiple blockchains: Ethereum, Tron, Solana, and others. The token is the same; the network determines speed, cost, and compatibility. Sending USDT on the wrong network results in permanent loss.
- USDC is Circle’s competing stablecoin. Both maintain the $1 peg but differ on issuer, reserve transparency, regulatory posture, and liquidity profile.
- Settling in stablecoins means receiving USDT or USDC instead of a bank wire when you sell Bitcoin. It is faster, available any time, and avoids the banking system; useful for buyers who plan to redeploy proceeds into another trade without returning to fiat.
- Stablecoins are useful but not risk-free. Issuer risk, brief depeg events, and regulatory uncertainty are real. Neither USDT nor USDC is insured by the FDIC or equivalent.
What Is USDT?
USDT stands for Tether USD, the USD stablecoin issued by Tether Operations.
Tether’s own transparency page states: “All Tether tokens are pegged at 1-to-1 with a matching fiat currency and are backed 100% by Tether’s Reserves.” USDT is the USD-denominated version of this.
The basic mechanic: Tether issues USDT tokens and holds a corresponding reserve of assets backing them.
When someone redeems USDT for USD, Tether removes the tokens from circulation and releases the corresponding fiat from reserves.
This creation and redemption cycle is what maintains the 1:1 peg.
USDT operates on multiple blockchains simultaneously.
The same $1 value applies regardless of which chain you use, but the speed, cost, and compatibility depend on the network.
What USDT is not: it is not a bank deposit and is not FDIC-insured.
It is not issued by a government or central bank.
It is not the same as holding USD in a bank account.
It is a claim on Tether’s reserves, and the stability of that claim depends on Tether’s reserve management and operational solvency.
How the Dollar Peg Works
A stablecoin peg works through a combination of reserve backing and market arbitrage.
Tether maintains reserves (consisting of cash, US Treasury bills, and other assets) equal to or greater than the value of all USDT tokens in circulation.
If USDT trades below $1 on the open market, arbitrageurs buy it cheaply and redeem it with Tether for $1, pocketing the difference.
This buying pressure pushes the price back toward $1.
If USDT trades above $1, Tether can issue new tokens to increase supply, bringing the price back down.
This mechanism works as long as: the reserves are real and accessible, Tether operates without interruption, and market confidence in the peg is maintained.
When any of these come into question (as happened briefly during periods of market stress), the peg can temporarily deviate.
In practice, USDT has maintained its $1 peg through significant market volatility, including multiple crypto market crashes, though brief deviations of fractions of a cent have occurred during peak stress events.
The Federal Reserve has studied stablecoin peg mechanisms and the conditions under which they can fail.
Their research note on stablecoins and crypto shocks covers how stablecoins respond to market stress events.
USDT vs USDC: How They Compare
USDT and USDC are the two dominant USD stablecoins.
Both maintain a $1 peg and serve similar functions.
The differences are in issuer, reserve transparency, regulatory positioning, and liquidity profile.
| USDT (Tether) | USDC (Circle) | |
| Issuer | Tether Operations, incorporated in El Salvador | Circle, a US-registered company |
| Market size | Largest stablecoin by market cap and daily trading volume. Verify current figure at publish. | Second-largest USD stablecoin. Verify current figure at publish. |
| Reserve backing | Cash, Treasuries, and other assets. Tether states assets exceed liabilities. Published periodically at tether.to/en/transparency. | 100% reserved in cash and short-duration US Treasuries. Monthly attestations published by a registered public accounting firm at circle.com/transparency. |
| Audit transparency | Periodic attestations – not a full GAAP audit. Tether has disclosed reserve composition but has faced questions about third-party audit rigor. | Monthly reserve attestations by a registered accounting firm. Circle has pursued greater regulatory transparency as a US-registered issuer. |
| Regulatory status | Subject to ongoing regulatory scrutiny in multiple jurisdictions. Tether settled with CFTC and New York AG. Not regulated as a bank or securities issuer. | US-based issuer. Has actively engaged with US regulators. Issued under money transmission licenses in applicable states. |
| Liquidity | Highest liquidity globally; most widely accepted on exchanges and OTC desks. Dominant in Asia-Pacific markets. | Very liquid. Preferred by US institutions and in DeFi applications. Strong presence in regulated venues. |
| Peg history | Has briefly traded below $1 during market stress events but returned to peg. No sustained depeg. | Briefly depegged during the SVB bank stress in March 2023 (USDC held reserves there) before recovering. |
| Best for | Maximum liquidity, global trading pairs, OTC settlement across international markets. | US institutional use, DeFi applications, and environments where regulated issuer status matters. |

The honest summary: USDT has higher liquidity and broader global acceptance.
USDC has more transparent reserves and a stronger regulatory standing in the US.
For OTC settlement purposes, both are widely accepted; the right choice depends on your platform, counterparty, and what you intend to do with the proceeds.
Which Network: The Most Important Practical Decision
USDT runs on multiple blockchains.
The same dollar value applies to all of them, but the network you send on determines the fees you pay, the speed of transfer, and, critically, whether the receiving address can actually accept the tokens.
| Network | Transaction Speed | Typical Fee | Common Use |
| Ethereum (ERC-20) | Minutes under normal conditions; slower during congestion | Variable gas fees – can be $5 to $50+ during peak demand | DeFi, large institutional transfers, most exchange defaults for USDT |
| Tron (TRC-20) | Fast – typically under 1 minute | Very low – often under $1 | High-volume international transfers, OTC settlement, Asia-Pacific markets |
| Solana (SPL) | Very fast – seconds | Very low – fractions of a cent | High-frequency applications, growing use in institutional settlement |
| BNB Chain (BEP-20) | Fast – typically under 1 minute | Low | Binance ecosystem, retail transfers |
WARNING: Sending USDT on the wrong network results in permanent, unrecoverable loss.
If you send TRC-20 (Tron) USDT to an address that only supports ERC-20 (Ethereum), the tokens arrive at a blockchain address that does not exist on Tron’s ledger and cannot be recovered. Always confirm which network the recipient accepts before sending.
Always verify the network designation alongside the wallet address.
How to avoid this: before sending any USDT, confirm the exact network with the recipient.
Most wallets and platforms clearly label which network an address belongs to (ERC-20, TRC-20, SPL, etc.). Never assume.
The token amount and dollar value are identical across networks; the network tag is what routes it correctly.
What Is Stablecoin Settlement?
Settlement refers to the final step of a trade: the actual transfer of funds to close the transaction.
In a Bitcoin trade, settlement can happen in two ways.
- Fiat settlement: proceeds from a Bitcoin sale are wired to your bank account in USD. This is a standard domestic bank wire. It is reliable, regulated, and familiar – but it requires a bank to be open, takes time to process (same day at best for domestic wires, 1 to 3 days common), and requires the seller to have bank details on file.
- Stablecoin settlement: proceeds from a Bitcoin sale are sent as USDT or USDC to a wallet address you specify. This happens on the blockchain – 24 hours a day, 7 days a week, in seconds to minutes depending on the network. No bank account required on the settlement side. No banking hours, no wire cutoffs, no correspondent bank delays.
Stablecoin settlement is particularly useful for buyers or sellers who plan to redeploy the proceeds into another crypto position immediately. Instead of converting proceeds to USD, waiting for a wire, and then wiring funds back to buy again, the full cycle stays on-chain in stablecoins.
It is also useful in cross-border contexts where wire transfers are slow or expensive, and in situations where the seller does not have a US bank account to receive a domestic wire.
The trade-off: stablecoins are not USD.
They are claims on an issuer’s reserves.
For proceeds you intend to hold long-term or spend in the real economy, a bank wire to a regulated account is more straightforward than managing a stablecoin position.
Are Stablecoin Proceeds Taxable?
Yes.
Under IRS guidance on digital assets, converting Bitcoin to USDT is treated as a taxable disposal of Bitcoin – the same as converting Bitcoin to USD.
You realize a capital gain or loss equal to the fair market value of USDT received (which equals its USD value, since 1 USDT = $1) minus your cost basis in the Bitcoin sold.
Holding USDT after the conversion is generally not a taxable event.
USDT has a stable $1 value, so no gain or loss accrues while you hold it at the same value you received it at.
Converting USDT back to USD is generally not a taxable event for the same reason.
Exchanging USDT for Bitcoin or another crypto at a later date is a new taxable disposal of the USDT.
Consult a qualified CPA for advice specific to your situation and the current tax year.
The Risks of USDT and Stablecoin Settlement
Stablecoins are useful tools that carry real risks.
Presenting them accurately is more useful than either dismissing or overstating those risks.
- Issuer and reserve risk. USDT’s stability depends on Tether maintaining reserves equal to or greater than tokens in circulation. If Tether’s reserves were insufficient, insolvent, or inaccessible, the peg could break. Tether has not failed in this way, but the risk exists and should be understood by anyone holding significant USDT balances.
- Depeg risk. Both USDT and USDC have briefly traded below $1 during market stress events. USDC depegged to approximately $0.87 during the Silicon Valley Bank stress in March 2023 before recovering. Brief depegs are recoverable; a sustained depeg would represent a significant loss for holders.
- Regulatory uncertainty. The US regulatory framework for stablecoins is still being developed. Legislation currently under discussion could impose new requirements on stablecoin issuers that affect how they operate or whether specific stablecoins remain accessible to US users. This risk is forward-looking and speculative but real.
- Wrong-network risk. As covered above, sending USDT on the wrong network results in permanent, unrecoverable loss. This is a user-level risk, not an issuer risk, but it is the most common cause of significant stablecoin loss among individuals.
- No deposit insurance. USDT is not covered by FDIC insurance or any equivalent government guarantee. Holding USDT is not the same as holding USD in a bank account. This is clearly stated by Tether and should be understood by anyone using stablecoins for settlement.

FAQ
What is USDT in crypto?
USDT is Tether USD, a stablecoin pegged to the US dollar, issued by Tether Operations.
1 USDT is designed to equal $1, backed by Tether’s reserves of cash, US Treasury bills, and other assets.
It operates on multiple blockchains, including Ethereum, Tron, and Solana, allowing fast, low-cost transfers of dollar-denominated value without using the traditional banking system.
Is USDT safe to hold?
USDT carries risks that USD held in a bank does not: issuer risk (dependence on Tether’s reserve management), depeg risk during market stress, and no FDIC insurance.
For short-term settlement and trading purposes, USDT’s track record of maintaining its peg through significant market volatility makes it widely used in crypto markets.
For longer-term holdings or larger amounts you intend to keep outside the trading ecosystem, a bank wire to a regulated account may be more appropriate.
What is the difference between USDT and USDC?
Both are USD stablecoins maintaining a $1 peg, but they differ in issuer, reserve transparency, and regulatory positioning.
USDT is issued by Tether, has the highest global liquidity and trading volume, and publishes periodic reserve attestations.
USDC is issued by Circle, a US-registered company, publishes monthly reserve attestations by a registered accounting firm, and has a stronger regulatory standing in the US.
For OTC settlement, both are widely accepted.
What does settling in stablecoins mean?
Stablecoin settlement means receiving USDT or USDC instead of a bank wire when you close a trade.
Instead of USD arriving in your bank account over one to three business days, USDT arrives in a wallet you specify within minutes, 24 hours a day, seven days a week.
It is useful for buyers who plan to redeploy proceeds into another crypto purchase without cycling funds through the banking system.
Can I lose money sending USDT?
Yes, in two specific ways.
First, if you send USDT on the wrong blockchain network – for example, TRC-20 USDT to an ERC-20 address – the funds are permanently lost and unrecoverable.
Always confirm the network with the recipient before sending.
Second, if you hold USDT and Tether’s reserves prove insufficient in a crisis scenario, the peg could break, and your holdings could be worth less than $1.
The second risk has not materialized historically, but it is a real structural risk to understand.
Is converting Bitcoin to USDT a taxable event?
Yes. The IRS treats converting Bitcoin to USDT as a taxable disposal of Bitcoin, equivalent to selling for USD.
Your gain or loss is calculated based on your Bitcoin cost basis.
See IRS Digital Assets guidance and consult a qualified CPA for your specific situation.
Which USDT network should I use?
It depends on the recipient’s supported networks and your priority.
TRC-20 (Tron) is the most common for high-volume OTC settlement – fast and very low cost.
ERC-20 (Ethereum) is most widely supported but can have high fees during network congestion.
Solana is very fast and cheap.
Always confirm with the recipient which network they accept before sending.
Network mismatches result in permanent loss.
