Best stablecoin for payments: how to choose between USDT and USDC (and why BUSD is gone)

Choosing a stablecoin is not choosing a coin. It is choosing a company whose promise you agree to hold instead of money. The ticker on your balance sheet is an IOU: the issuer says it will hand you a dollar for it. Everything that matters about that IOU is a property of the issuer — where it is incorporated, which regulator watches it, what it publishes about its reserves, how fast it actually pays out.

So the practical answer comes down to geography. If your customers and your costs are in the EU or the US, hold USDC — it is issued by a company licensed in Europe and supervised at home, which is the shortest answer to any question your bank or auditor asks. If your customers are in Asia, the Middle East, the CIS or Latin America, hold USDT — it is what your counterparties there already use, and USDC will cost you a conversion on the way out. Hold both only if you genuinely have two geographies, because a second coin means a second reconciliation and a second set of addresses.

BUSD is the whole lesson in one coin

BUSD did not crash. It was simply stopped.

New York's Department of Financial Services ordered Paxos, the issuer, to stop minting new BUSD; the announcement came on 13 February 2023. Then the exchange side moved first. Binance ended BUSD support on 15 December 2023, switched off withdrawals from 31 December 2023, and automatically converted remaining balances into FDUSD at 1:1. Binance made that call on its own. And the destination is worth noticing: FDUSD, not USDT.

Holders kept their money. What they lost was control of the timetable: a business with BUSD as its main treasury asset found out from an exchange announcement, on the exchange's schedule, and ended up in an asset it had not chosen. That is the actual risk with stablecoins, and it has nothing to do with the price chart.

So, plainly: do not accept BUSD in new payments, and do not hold it as a primary asset.

If you still hold some, be careful about which exit is actually yours. Paxos remains obliged to redeem BUSD at 1:1 for dollars, or convert it into USDP — Paxos still publishes the redemption page, and the New York regulator's consumer alert confirms the 1:1 obligation. But direct redemption with any issuer normally runs through an account and a contract, with minimums usually set for institutions. If your balance is large, ask Paxos about terms. If it is a few thousand dollars, your realistic route is to convert it on a venue that still lists it, at whatever price and spread you get there. Find out which of those two you are before you plan the trade.

What you are actually comparing

Picking an issuer turns a vague question — "which coin is safer" — into a short list with checkable answers.

• Where is the issuer incorporated, and who supervises it? This determines whether a regulator can force a change, and whether anyone will notice before you do.
• What does it publish about reserves, how often, and who signs it? An attestation and an audit are different things. An attestation confirms that assets existed on a given date. An audit examines the accounting system that produces the numbers. Most issuers publish attestations. Read the word on the document.
• What is the reserve made of? Treasury bills behave very differently from commercial paper or secured loans when everyone redeems at once.
• How do you actually get dollars back? For a small company, almost never from the issuer: direct redemption usually runs on a contract with institutional minimums. Your exit is a sale — on an exchange, through an OTC desk, or through whatever conversion your payment provider offers — at the price available that day. Liquidity is only visible on the way out.
• Which chains does the issuer support, and can that list shrink? It can. It has.

USDT (Tether): the widest acceptance

New to the coin itself? Start with what USDT is.

Issuer: Tether, incorporated outside the United States.

Size: roughly $184.6 billion of USDT in circulation as of 30 June 2026, with reserves exceeding liabilities by $4.11 billion, according to Tether's Q2 2026 attestation by BDO.

Reporting: a quarterly attestation by BDO, plus a first full audit opinion from KPMG U.S. covering the year ended 31 December 2025. That audit is the substantive change: for a decade nobody had examined the books. It covers one year.

Chains: officially issued on 14 networks — Ethereum, Avalanche, BNB Smart Chain, Kava, Celo, Kaia, Tron, Liquid, Solana, Polkadot AssetHub, Tezos, Near, TON and Aptos, per Tether's supported protocols page. The TON line has a quirk of its own: what sending on TON costs, and why the fee is paid in Gram.

Regulatory standing: no EU authorisation, and no US federal stablecoin supervisor, the issuer being incorporated abroad — the position as of 1 September 2026.

Where it is strong: reach. Outside the EU and the US, USDT is the unit counterparties quote in and the pair local exchanges list against. If your suppliers or customers sit there, it moves without an extra conversion.

Where the risk sits: history and disclosure. The US Commodity Futures Trading Commission fined Tether $41 million on 15 October 2021, and the CFTC's order found that between June 2016 and February 2019 the company held sufficient fiat reserves on only 27.6% of the days examined. That covers 2016 to 2019; quarterly attestations and a completed audit did not exist then. It is still why Tether's numbers get read more sceptically than Circle's.

USDC (Circle): the tightest supervision

Issuer: Circle, a US company.

Size: $73.7 billion of USDC in circulation as of 27 August 2026, per Circle's USDC page. Roughly two and a half times smaller than USDT, which matters for depth in large OTC corridors and barely registers for a business receiving invoices.

Reporting: monthly. Circle says on its transparency page that a Big Four accounting firm provides monthly third-party assurance that reserves exceed USDC in circulation; the firm signing that assurance is not named there. Separately, Circle names Deloitte & Touche LLP as the independent auditor of its own financial statements, a role it has held since fiscal 2022. Two different documents, possibly two different signatures. The frequency is what you can rely on: monthly shortens the gap between something going wrong and you seeing it.

Chains: more than thirty, and Circle's own site gives two counts — the multi-chain page says natively supported on 37 networks, while the FAQ on the same page says 35 as of 29 June 2026. Either way the footprint is wider than USDT's, with one awkward absence: TRON. If your counterparties expect to pay over TRON, that is a hard constraint.

Regulatory standing: EU-licensed since 1 July 2024, and a US issuer inside US supervision at home — the position as of 1 September 2026.

Where it is strong: the paperwork. A European bank or auditor will not blink at USDC on the balance sheet, and it came through the EU's 2025 stablecoin clear-out untouched.

Where the risk sits: the banking system it integrates with so well. In March 2023, $3.3 billion of USDC reserves — about 8% of the backing — were stuck in the collapsed Silicon Valley Bank, and USDC traded below a dollar over the weekend. Once the FDIC guaranteed deposits on 12 March 2023, Circle confirmed the reserve risk was removed and the de-peg closed. The reserve was made whole. Whoever sold during those two days sold at the price on offer.

The rules: where each coin stands right now

This section describes the position as of 1 September 2026 and is not legal advice.

In the European Union

Circle obtained an EMI licence — the licence category for a regulated payments firm — from the French regulator ACPR on 1 July 2024, and issues USDC and EURC in the EU under MiCA, the bloc's crypto-asset regulation. Circle published the milestone itself.

Tether did not apply for authorisation. On 17 January 2025 the EU securities regulator ESMA told service providers to stop offering stablecoins that do not comply with MiCA, with a sell-only window to 31 March 2025 — the ESMA statement is public. USDT came off regulated EU venues as a result.

The shorthand is wrong: USDT is not banned in the EU. Holding it and transferring it are not prohibited there. It was delisted from supervised platforms because its issuer did not seek the licence. That is the venues' problem, and it leaves your own holding where it is.

In the United States

The GENIUS Act — Public Law 119-27, originally S.1582 — is US federal law, signed on 18 July 2025. The full text sits on govinfo. It sets out what a permitted payment stablecoin issuer will have to do:

• hold reserves of at least 1:1 in a narrow list of permitted assets;
• publish the composition of those reserves monthly, examined by a registered public accounting firm and certified by the CEO and CFO;
• and, above $50 billion in issuance, produce annual audited financial statements under PCAOB standards.

Timing: as of 1 September 2026 the regime is not fully in force. It takes effect on the earlier of 18 January 2027 or 120 days after regulators finalise their rules, and US agencies were still writing those rules through 2026. So what an issuer publishes today is its own practice, not yet compliance with this statute.

Perimeter, which is the part that answers "does this touch me". The law governs issuers within US jurisdiction. Circle is inside it. Tether is incorporated outside the United States, so this statute puts no US federal supervisor over it. What changes for you is who would intervene, and how early you would hear about it. Legality is a separate question per jurisdiction: in the EU, holding and transferring USDT are not prohibited; anywhere else, ask your adviser.

Three things that are true whichever coin you pick

An issuer can freeze a specific address

The mechanism: each issuer keeps a blacklist inside the token's smart contract. Once your address is on it, the tokens stop moving — you still see the balance, you simply cannot send it. The issuer acts alone, usually after a law-enforcement request, and needs no cooperation from you, your wallet or your exchange.

It happens at scale. Tether has supported freezing more than $344 million in USDT working with OFAC and US law enforcement. Circle blocked addresses on the OFAC sanctions list connected to Tornado Cash in August 2022. Both follow sanctions listings and law-enforcement requests aimed at named addresses: a freeze lands on a particular address, not on all USDT.

How does an ordinary business get caught in one? Through who pays it. Coins arriving from a customer whose own funds trace back to a sanctioned entity or a theft can drag the receiving address into an investigation.

And if it happens, what is the way back? Thinner than you would like. On the issuers' public pages there is no appeal procedure for a frozen holder to follow — no form, no timeline, no criteria — though Tether does run a general support channel. Neither company describes publicly how an unblocking decision gets made. That is an absence of description, not proof that nothing can be done; in practice you would find out through a lawyer and through the authority that requested the action, while the balance sits immobile.

A depeg is a pricing problem before it is a solvency problem

Your prices are in dollars and settlement arrives in a token briefly not worth one. An invoice settles at the market price that day, the customer considers it paid in full, and you are short the gap. Converting out locks that gap in; waiting means holding an asset whose recovery you do not control; your provider's auto-conversion executes at whatever the market says that hour. And these episodes tend to start when the banks holding the reserves are closed, so the resolution arrives on someone else's clock.

The operational play-by-play is a separate read: what a depeg does to a business.

One ticker on different chains is different tokens

This is the part that costs businesses real money. USDT on Tron and USDT on Ethereum are separate tokens that happen to share a name and a price. Send one to an address on the other chain and it is usually gone.

And the issuer owns that list of chains. On the same supported-protocols page, Tether states it no longer issues USDT — and is not obliged to redeem it — on five legacy networks: Kusama, Bitcoin Cash SLP, Omni Layer, EOS and Algorand. Balances stranded on a deprecated chain are a concrete risk, and the only warning is a page on the issuer's site.

So if you plan to accept USDC and USDT on multiple blockchains, treat each issuer's chain list as closed, re-read it quarterly, and enable the smallest set your customers actually use. Choosing between those networks is its own decision: here is which network to enable and what it costs.

The rest of the field, briefly

DAI. Crypto-collateralised: smart contracts hold over-collateralised crypto, and no company holds dollars for you. Genuinely different risk, but it adds governance you cannot audit and a redemption path your accountant will not enjoy.

EURC (Circle). A euro stablecoin from the same issuer as USDC, issued in the EU under MiCA. Worth it if your revenue and costs are both in euros, since a dollar stablecoin makes you carry an FX position. Liquidity is far thinner, so check you can convert.

PYUSD. The PayPal-branded dollar stablecoin. Fine as a receiving option if a customer insists; keep it out of a small treasury, where it concentrates you into a coin whose reach depends on one consumer platform.

FDUSD. The coin BUSD balances were converted into at the end of 2023. Accept it if you must, convert it promptly, do not accumulate it.

The set of coins you can accept is far wider than the set worth holding.

How to decide your own case

A working policy for a small company fits in five lines.

1. Pick one primary asset, matched to your geography. EU or US exposure: USDC. Asia, MEA, CIS, LatAm: USDT. When customers sit on one side and suppliers on the other, follow the side you pay: the conversion loss lands when money leaves you, not when it arrives.
2. Deal with the pile you already have — separately from the rule going forward. Switch the incoming flow first, since that is free. Then let the old balance run down through normal withdrawals: a wholesale swap pays spread on the entire amount to fix a problem that mostly disappears as the balance turns over. Convert the lot only if the coin you are holding is the wrong one for a hard reason — a supplier who cannot accept it, a bank that questions it, an issuer under a regulatory cloud.
3. Add a second coin only when a second geography is real — meaning invoices you genuinely cannot settle in the first coin. Two coins is two reconciliations.
4. Keep the standing balance small, and know what "withdrawing" actually buys you. Moving funds off the provider's balance to your own wallet, on a fixed schedule, removes the intermediary: its solvency, its holding periods, its account decisions. It does not remove the issuer, because the blacklist lives inside the token and reaches your own wallet just as easily. Only converting into fiat takes you out from under the token itself. Run the schedule against the first risk; size the whole stablecoin position against the second.
5. Re-read your issuer's supported-chain page and latest attestation once a quarter. Ten minutes. It is the only early warning you get.

Still deciding whether to accept stablecoins at all? Start there first. And if the whole setup is new, the complete guide to crypto payments for business covers the ground this article picks up from.

What will actually be sitting on your balance

One catch: once you accept crypto payments through a provider, that provider often decides which coin ends up there.

Some services credit you whatever the customer paid with, so your balance becomes a spread of assets to reconcile. Others convert everything into a single asset the moment it lands, so the provider's rule sets your treasury. Both work; you need to know which one you are on. With CryptumPay, for example, an incoming payment is converted into USDT at the moment it is credited — so on that balance the service's rule makes the stablecoin choice.

Be equally clear about what a provider actually supports. Of the stablecoins, CryptumPay works with USDT — USDC and the others are not available there. A marketing list of "supported coins" and the list you can genuinely hold and withdraw often differ.

Ask these in writing, before you sign

1. Which coins do you credit, and on which chains? Get the actual list, chain by chain.
2. Do you credit what the customer paid, or convert on receipt? If it converts, into what, at what rate, and who sets the rate.
3. What are the withdrawal conditions? Minimum amount, holding period, any fee on top of the network fee, restrictions on the destination address. These vary enormously between providers and rarely appear in the pricing table.
4. What happens if an incoming payment arrives on a chain you do not support? "Contact support" is an answer. Silence is not.
5. What does a payment cost, all in? As one concrete reference point: CryptumPay charges 1% on a successful payment, and manual withdrawal from the dashboard is available at any time with no minimum amount. Ask every provider for the same two numbers and compare them like for like.

Hand the answers to whoever closes your books. If you have not mapped how stablecoin flows land in your ledger, reconciliation and accounting is the next read.

FAQ

What is the best stablecoin for payments in 2026? There is no single winner, because the answer follows your customers: USDC for EU and US business, USDT for most other markets.

Do I need to accept more than one stablecoin to accept crypto payments? Usually not. One widely used coin on the one or two chains your customers actually use covers most volume, and every extra option adds a reconciliation line.

What happened to BUSD, and do I need to do anything? Paxos was ordered to stop issuing it, and Binance auto-converted balances into FDUSD at 1:1 at the end of 2023. Redemption at Paxos remains available in principle; the practical exit for a small balance is a sale on a venue.

The short version

If you accept crypto payments, stablecoin choice is issuer choice. Pick by the side you pay, hold one coin unless you truly need two, move balances off the provider regularly, and get its answer in writing about what it credits and what it converts.

And keep BUSD in mind as the shape of the risk. The coin that hurts you is not the one that crashes. It is the one that gets switched off while you were not looking.
