USDT vs USDC: Which Should You Hold on a Card?

USDT vs USDC is one of the first questions people ask when they start holding digital dollars. Both are designed to be worth one US dollar, and for everyday spending, the differences are smaller than most guides suggest. With Cashi, you can hold either one, or both, and spend it anywhere Visa is accepted. This guide compares the two so you can decide which makes sense for you to hold on a card.

What’s the Difference Between USDT and USDC?

USDT and USDC are digital dollars: balances designed to keep a steady value of one US dollar each. USDT (Tether) is issued by Tether, and USDC (USD Coin) is issued by Circle. Each issuer publishes information about the reserves it holds to back its digital dollar.

Because both follow the dollar, a balance of 100 USDT and a balance of 100 USDC should buy roughly the same things. The differences show up in who issues them, which networks carry them and which people or services you deal with use each one.

USDT vs USDC at a Glance

Question	USDT	USDC
Who issues it?	Tether	Circle
What is it designed to be worth?	One US dollar	One US dollar
Networks Cashi accepts	Ethereum, Arbitrum, BNB Chain, Solana, Tron	Ethereum, Arbitrum, Base, BNB Chain, Polygon, Solana
Spend with the Cashi card	Yes	Yes
Cash out to local currency with Cashi	Yes, where cash out is available to you	Yes, where cash out is available to you

Both run on several networks each, so the network often matters more than the asset when you send money.

Is USDT or USDC Better for Spending?

For spending, either works. A card converts your balance at checkout, so the shop never sees whether you paid from USDT or USDC. What matters more is how money reaches you and where it needs to go next.

• USDT may suit you if clients, employers or family pay you in USDT. Many people receive it on the Tron network, where fees are very low.
• USDC may suit you if you’re paid in USDC or use networks such as Base or Polygon.
• Holding both can make sense if money arrives in both. You don’t need to convert one into the other just to spend it.

Swapping between the two just to switch usually adds a fee without changing what your money can buy, so many people simply keep what they receive.

Is USDT or USDC Safer?

Cashi does not provide recommendations on which digital dollar to hold.

USDT is issued by Tether and USDC is issued by Circle. Both issuers say their digital dollars are backed by reserves, and each makes information about those reserves publicly available, including reserve reports. Before you decide, we encourage you to review that information yourself: Tether’s transparency page and Circle’s transparency page.

Neither USDT nor USDC is a bank deposit or covered by deposit insurance; like any digital asset, neither is risk-free, and each depends on its issuer. Cashi doesn’t issue or guarantee either one.

How to Spend USDT or USDC With a Card

To spend USDC or USDT with Cashi, deposit it on a supported network, wait until it shows as available, and pay online or in store with Google Pay. If you hold both, set the order once in Settings > Asset spending order, so the card knows which balance to use first.

The card works wherever Visa is accepted, online and in-store. You can also pay with USDC or USDT directly where a merchant accepts it, but a card is simpler for everyday purchases. For step-by-step details, see our guide to spending crypto with a debit card, and for paying a merchant directly, how to pay with USDT.

Fees and Networks

Fees depend on the network more than on the asset. Ethereum can be more expensive when it’s busy, while Tron, Solana and Base are usually much cheaper. Sending on a network the recipient doesn’t support can mean the money never arrives, so always match the network named on the receiving screen.

With Cashi, card payments in US dollars have no FX (foreign exchange) conversion fee, and purchases in other currencies carry a 1% FX conversion fee. The fees are the same whether you spend USDT or USDC. The full list of networks is in the Help Center guide to supported assets and networks.

Things to Keep in Mind

• Both are designed to be worth one dollar, but their market price can move slightly above or below it.
• Each one depends on its issuer. Some people hold both so they don’t rely on a single issuer.
• A dollar balance still moves against your local currency, which is often the reason people hold it.
• Keep records of what you receive and spend, since tax rules differ from place to place.
