Are USDT and USDC Safe? How a Stablecoin Differs From a Bank Account

by PayFi · 5 October 2026 · Stablecoins

A stablecoin is a digital dollar you hold yourself, not a deposit a bank holds for you. It moves fast and needs nobody's permission, but no government insures it. Treat it like cash with a receipt, not like savings in a bank.

Bitcoin and most crypto
  1. No company, no reserve of dollars
  2. Price = what the next buyer pays
  3. More sellers than buyers: price falls
  4. 2022: from $43,319 to $16,604
A stablecoin (USDC, USDT)
  1. A business sends $1 to the issuer
  2. Issuer makes 1 coin, keeps $1 in reserve
  3. Coin returned: $1 paid back, coin destroyed
  4. That swap holds the price near $1

Held at $1 by reserves, not by deposit insurance.

Bitcoin prices for 2022 from Fox Business. Direct swaps with the issuer are for businesses such as exchanges (Circle). The FDIC lists crypto assets as not covered by deposit insurance. Example only.

The balance that looked like savings

Let's meet someone we will call Nadia. She is not a real person, but many freelancers will recognize her.

Nadia designs websites for small businesses in other countries. For the past year, most of her clients have paid her in USDC. It arrives in seconds, there are no bank transfer fees, and nobody asks her to fill in forms. Her earnings sit in the app of a crypto exchange, where the screen shows a clean number: 3,000 USDC. Next to it, in smaller letters, it says "≈ 3,000 USD".

To Nadia, it feels exactly like a bank account. There is a balance. There is an app. There is a login. The number does not jump around like Bitcoin. She has started to think of it as her savings.

One evening a friend asks her a simple question: "If that exchange went bust tomorrow, who would give you your 3,000 dollars back?"

Nadia does not know.

This essay is about that question. Not to scare anyone away from stablecoins, which are a very useful tool, but to make clear what kind of tool they are. A stablecoin and a bank account can show the same number on a screen. Underneath, they are different things, with different protections and different risks. Once you see the difference, you can use stablecoins for what they are good at, and keep your savings where they are best protected.

The old belief: a digital dollar is a bank dollar

The belief Nadia slipped into is easy to understand. A balance in an app that says "3,000 USDC ≈ 3,000 USD" looks just like a balance in a banking app. Both are numbers on a screen. Both are called dollars. Both can be sent to someone else.

But "the same number on a screen" hides three very different questions:

  1. Who owes you that money?
  2. Who protects you if they cannot pay?
  3. Who can stop you from using it?

A bank account and a stablecoin give different answers to all three. And the answers also change depending on where you keep your stablecoins: in an exchange account, or in your own wallet.

Let's take them one at a time.

How a bank account works

When you put money in a bank, you are, in a legal sense, lending it to the bank. The bank uses most of it to make loans and investments. In return, it promises to give your money back when you ask.

Because banks can fail, many countries protect ordinary depositors with deposit insurance. In the United States, for example, the Federal Deposit Insurance Corporation, or FDIC, insures deposits up to 250,000 dollars per depositor, per insured bank, for each account ownership category. The FDIC also says clearly that crypto assets are not covered by that insurance (FDIC). Other countries have their own schemes with their own limits.

A bank account also comes with other protections people rarely think about. If you forget your password, the bank can reset it after checking who you are. If someone steals your card, the bank can often reverse the charges. If you die, the money goes to your heirs through a known process.

There are costs, of course. Banks can be slow, especially across borders. They can freeze accounts. In many countries, people cannot get an account at all, or cannot hold dollars in one. Those costs are exactly why stablecoins became popular. But it is worth being clear about what a bank account gives you in return for those costs: a promise backed by a regulated institution, and for most ordinary amounts, a government guarantee.

How other crypto works

Before we look at stablecoins, it helps to see how most other crypto works, because stablecoins were built to fix one of its biggest problems.

Bitcoin has no company behind it and no reserve of dollars. Nobody promises to swap your bitcoin for a fixed number of dollars. Its price is simply what the next buyer is willing to pay. When more people want to buy than sell, the price rises. When more want to sell, it falls.

That is why its price can move so much. Bitcoin started 2022 at 43,319 dollars and ended the year at 16,604 dollars, a fall of 64.2 percent (Fox Business). In other years it has risen just as sharply. For someone who wants to invest and accept that risk, that is a choice. For someone who wants to be paid 3,000 dollars and still have 3,000 dollars next month, it is a problem.

How a stablecoin works

A stablecoin like USDC or USDT solves that problem by adding a company and a reserve.

When a business sends one dollar to the issuer, the issuer creates one coin and keeps the dollar, or something very close to a dollar, in its reserves. When a business returns one coin, the issuer pays out one dollar and destroys the coin. Circle, the company behind USDC, describes its service for this as being for institutional customers such as exchanges, wallet providers, banks and trading firms, and says USDC can be redeemed one for one for US dollars through it (Circle).

Notice who that is for. Not Nadia. Ordinary people usually cannot swap directly with the issuer. Tether, the company behind USDT, has required a minimum of 100,000 dollars to redeem directly, along with an identity check and a fee, according to a 2022 report (CryptoSlate).

So how does Nadia's USDC stay at a dollar? Through the businesses that can swap. If USDC traded at 98 cents on an exchange, those businesses could buy it cheaply and redeem it with Circle for a full dollar. Their buying pushes the price back to a dollar. If it traded above a dollar, they could create new coins and sell them, pushing the price back down. Nadia benefits from this without ever talking to Circle.

That is the whole difference from Bitcoin. Bitcoin's price is whatever the market says. A reserve-backed stablecoin's price is held close to one dollar by a company that promises to swap, and by the reserves it keeps to keep that promise.

Who owes you, and who protects you

Now let's go back to the three questions.

Who owes you the money? With a bank account, the bank owes you. With a stablecoin, the issuer owes the holder of each coin a dollar, through the redemption system we just described. But if your stablecoins sit in an exchange account, there is another layer: the exchange holds the coins, and what you have is the exchange's promise to give them to you.

Who protects you if they cannot pay? With a bank account, deposit insurance protects ordinary amounts. With a stablecoin, there is no deposit insurance. Your protection is the issuer's reserves, the checks on those reserves, and the rules the issuer must follow. In the United States, the GENIUS Act, signed on July 18, 2025, requires covered stablecoins to be backed one for one by US dollars or other low-risk assets (Wikipedia). That is an important rule. It is not the same as a government guarantee.

Who can stop you from using it? A bank can freeze your account. A stablecoin issuer can freeze specific addresses. Tether said in February 2026 that it had frozen about 4.2 billion dollars in funds linked to illegal activity, working with more than 310 agencies in 64 countries (ForkLog). An exchange can also freeze or close your account under its own rules. In your own wallet, only the issuer's freeze applies, and in practice it is used mostly when law enforcement is involved.

So the honest summary is this. A stablecoin replaces the bank's promise with the issuer's promise, and replaces deposit insurance with reserves and rules. For many people, that is a good trade, especially where banks are slow or hard to reach. But it is a trade, not the same thing.

When the reserves were tested

It helps to look at one real moment when a well-known stablecoin's reserves were put under pressure, because it shows both the strength and the limit of the design.

In March 2023, a US bank called Silicon Valley Bank failed. Circle said that 3.3 billion dollars of USDC's reserves were held at that bank. Over a weekend, people feared that part of the reserves might be lost, and USDC fell below 87 cents (CNBC). Then US authorities said that all deposits at the failed bank would be protected, and on March 13, USDC returned to one dollar (Crowdfund Insider).

Look at what that weekend shows. The stablecoin itself had no insurance. Its price recovered because the bank that held part of its reserves was protected. In other words, a stablecoin with cash reserves is partly exposed to the same banking system it is often compared with. Its reserves are only as safe as the places they are kept.

Circle says its reserves today are held separately from its own operating funds, mostly in a money market fund that holds cash, short-dated US government debt and overnight repurchase agreements, with the rest in bank deposits (Circle). That is a sensible way to reduce the risk. It does not remove it.

Not every "stablecoin" is the same

Before going further, it is important to know that the word "stablecoin" has been used for very different designs, and one of them failed badly.

TerraUSD, known as UST, called itself a stablecoin. But it was not backed by a reserve of dollars. Instead, it tried to hold its price at a dollar with an automatic system linked to another coin called LUNA. In May 2022, people lost confidence, the system broke, and UST became essentially worthless within days. According to the Corporate Finance Institute, more than 50 billion dollars of value in UST and LUNA was destroyed (CFI).

The lesson is not that all stablecoins are dangerous. It is that "stable" is a claim, and the claim is only as strong as what backs it. USDC and USDT are backed by reserves that their issuers report on. UST was backed by a mechanism that depended on confidence in another coin. When choosing a stablecoin to hold, the first question is always: what is behind it, and who checks?

Where you keep it changes everything

This is the part Nadia's friend was really asking about. Even with a well-backed stablecoin, where you hold it changes your risks a lot.

In an exchange account, you do not hold the coins yourself. The exchange holds them and owes them to you. If the exchange is honest and solvent, that works well, and it feels just like a bank. If it is not, you can lose access. That is what happened at FTX, once one of the largest crypto exchanges. In November 2022, customers rushed to withdraw, in what the news described as the crypto version of a bank run, and the exchange turned out to be short billions of dollars. It filed for bankruptcy on November 11, 2022 (PBS NewsHour). Customers who held stablecoins there were not protected by the stablecoin's reserves, because the problem was not the stablecoin. It was the place where it was kept.

In your own wallet, you hold the coins directly. No exchange can go bust and take them with it. But now you are the bank. There is no password reset. If you lose your recovery words and your phone, nobody can restore your coins. If you type your recovery words into a fake website, the person behind it can take everything, and nobody can reverse it.

Neither choice is free of risk. They are different risks. An exchange asks you to trust a company. A wallet asks you to trust yourself. Many people use both: a wallet for the money they use day to day, and a well-known, licensed exchange only for changing money in and out, without leaving large balances there for long.

Side by side

Here are the three places Nadia's 3,000 dollars could live, compared on the things that matter most.

In a bank account:

As stablecoins in an exchange account:

As stablecoins in her own wallet:

None of the three is best at everything. A bank protects savings best. A wallet gives the most control and the fewest middlemen. An exchange sits in between. Most people who use stablecoins well use more than one of these, each for what it is good at.

The risk that has nothing to do with the coin

There is one more risk worth naming, because it hurts more people than any of the others: scams.

The US Federal Trade Commission reported that consumers lost more than 12.5 billion dollars to fraud in 2024. Of that, 1.42 billion dollars was paid using cryptocurrency, and investment scams alone accounted for 5.7 billion dollars across all payment methods (SecurityWeek).

Scammers like crypto for the same reason honest sellers do: payments are fast and final. A bank transfer to a scammer can sometimes be stopped. A stablecoin payment to a scammer usually cannot.

So the habits that protect you are simple and worth repeating:

Stablecoins do not pay interest by themselves

That last point deserves its own section, because it is another place where the bank picture misleads people.

A bank may pay you interest on your savings, because it lends your money to others. A stablecoin, sitting in your wallet, does nothing of the kind. One USDC today is one USDC next year. The issuer earns income on its reserves, but that income goes to the issuer, not to you.

Some platforms offer interest on stablecoins anyway. When they do, the money for that interest has to come from somewhere, usually from lending your coins to other people or businesses. That can work, but it adds a new risk on top of the ones we have already covered: the risk that the borrowers do not pay back. A stablecoin that you lend out is no longer simply a digital dollar. It is a loan, with all the risks of a loan.

None of this means you should never earn anything on your money. It means you should know when you have moved from holding a digital dollar to making an investment.

A four-question test for any place that holds your money

You do not need to remember every detail in this essay. You can carry four questions instead, and ask them about any app, exchange, wallet or service that shows you a balance.

  1. Who owes me this money? A bank, an exchange, an issuer, or nobody because I hold it myself?
  2. What protects me if they cannot pay? Deposit insurance, reserves that are checked, rules they must follow, or only their word?
  3. Who can stop me from using it? The company, the issuer, a court, or nobody?
  4. How do I get out, and how long does it take? Can I move the money to my own wallet or bank today, and what does it cost?

If you cannot answer one of these questions about a place that holds a lot of your money, that is your sign to find out, or to hold less there. The questions work the same way for a bank, a payment app or a stablecoin. They just give different answers.

How to hold stablecoins sensibly

Putting all of this together, here is a practical way to think about stablecoins if you sell or buy online.

Use them for what they are best at: moving money. They are excellent for getting paid quickly, paying people in other countries, and avoiding slow and expensive transfers.

Think of your balance as cash in your pocket, not savings in a vault. It is real money, and it is yours, but it is not insured. Keep an amount that matches what you need for working and paying, not your whole life savings.

Decide where your long-term savings live. For many people, that is still a bank or another regulated institution where deposit insurance applies. For people whose local currency is losing value fast, or who cannot open a dollar account, keeping more in stablecoins can make sense. That decision is yours, and it depends on your country and your situation.

Split what you hold. Do not keep everything with one exchange or one issuer. Some in a wallet, some changed into local money, perhaps some in each of USDT and USDC, in whatever mix fits you.

Prefer well-backed coins. Choose stablecoins whose issuers publish regular reports on their reserves. Be very careful with anything that calls itself stable but cannot show what backs it.

Keep records. Note what you were paid, when and for what. Your payments are on the blockchain, but your own list is easier to read at tax time, and you are still responsible for taxes where you live.

Why people still choose stablecoins

After all these warnings, it is fair to ask why so many people use stablecoins at all. The answer is that, for many of them, the bank picture we started with is not available.

The World Bank's Global Findex survey estimates that about 1.3 billion adults in the world still have no account at a bank or mobile money provider. The same survey found that 86 percent of adults have a mobile phone (World Bank). For many people in that gap, a phone with a wallet app is the easiest way to hold dollars at all.

Even people with bank accounts often pay a lot to move money across borders. The World Bank found that in the first quarter of 2025, the global average cost of sending 200 dollars abroad was 6.49 percent, and 14.55 percent through banks (World Bank).

So the choice is not between a perfect bank account and a risky stablecoin. For many sellers and buyers, it is between a slow, expensive or unavailable bank route and a fast, cheap stablecoin route with risks they can understand and manage. Knowing those risks clearly is what turns a stablecoin from a gamble into a tool.

Questions people ask

If USDC is backed by dollars, why is it not insured? Deposit insurance covers deposits at insured banks. A stablecoin is not a bank deposit. It is a claim on the company that issues it, backed by the assets it holds. The FDIC lists crypto assets among the things its insurance does not cover.

What if the issuer itself goes bankrupt? Then holders would depend on the reserves being there and being paid out to them. That is why it matters that reserves are held separately from the issuer's own money, checked regularly and governed by rules. It is also why holding very large amounts in a single stablecoin for a long time deserves careful thought.

Is it safer in an exchange or in a wallet? It depends on which risk you would rather carry. An exchange can fail or freeze your account. A wallet can be lost or stolen if you do not protect your recovery words. A good habit is to keep only what you need on an exchange, and to protect your wallet carefully.

What happens to my stablecoins if something happens to me? With an exchange account, there is usually a process for heirs, depending on the exchange and the country. With a wallet, nobody can reach the coins without the recovery words. If you hold a meaningful amount in a wallet, think about how a trusted person could access it if needed, without putting the words where a stranger could find them.

Why a payment tool should not act like a bank

There is a reason this essay matters for how a payment link is designed, and it goes back to Nadia's friend's question.

Many payment services quietly become banks. They collect sellers' money into a balance on their own website, hold it for days or weeks, and pay it out on a schedule. That can be convenient. But it means sellers have the risks of a bank, a company holding their money, without the protections of a bank, such as deposit insurance.

A payment link that pays sellers directly avoids that. When a buyer pays, the money is split on the blockchain in one step and the seller's share goes straight to the seller's own wallet, usually within about 20 seconds. There is no running balance of sellers' money for the service to hold, lend out, lose or freeze. The seller decides where the money goes next: keep it in a wallet, move it to an exchange, or change it into local money.

That design does not make the seller's stablecoins insured. Nothing can do that. But it removes one layer of risk entirely. The fewer companies that hold your money along the way, the fewer places it can get stuck.

What it means for buyers

If you are on the buying side, most of this essay applies to you too, in a smaller way.

When you hold some USDT or USDC to pay for things online, keep an amount that matches what you plan to spend. Buy it from a licensed exchange or service in your country. If you keep it in a wallet, protect your recovery words like the key to your house. If you keep it on an exchange, do not leave more there than you need.

And remember that a payment you send is final once the order is complete. That is part of what makes stablecoins fast and cheap. It also means the best protection is to buy from people you trust and to check the address and network before you send.

Back to Nadia

Let's return to Nadia and her friend's question: if the exchange went bust tomorrow, who would give her 3,000 dollars back?

The honest answer, in her case, is: possibly nobody. Not because USDC is weak, but because her coins are held by an exchange, and no deposit insurance covers them.

So Nadia makes a few changes. She keeps a working balance in her own wallet, enough for a month of expenses and payments, and writes her recovery words on paper that she keeps somewhere safe. She changes part of her earnings into local money each month and keeps that in her bank. She stops thinking of the exchange as a savings account and uses it only to change money in and out. Nothing about how she gets paid changes. Her clients still pay her in USDC within seconds.

What changed is her picture of what she holds. The old belief said that a digital dollar in an app is the same as a dollar in a bank. The new one is more precise: a stablecoin is a digital dollar backed by a company's reserves, not by a government guarantee. It is excellent for moving money and good for holding what you need to use. For everything else, you choose, knowing exactly what protects you and what does not.
