At first glance, it seems more logical: sell Bitcoin, withdraw dollars to your bank account, and wait for the next opportunity. Why do traders hold USDT? Several reasons.
Speed of Re-entering a Position
Bitcoin can drop 10% in a couple of hours. If your money is in the bank at that moment, you won't be able to get it back to the exchange in time — crypto deposits usually take from hours to several days. USDT on the exchange allows you to buy the falling BTC within a minute of your decision.
Low Withdrawal and Deposit Fees
Transferring fiat from an exchange and back costs money. SEPA in the EU: free, but 1-2 days. Wire transfer in the US: $20-50, one day. Cards on exchanges: 2-4% fee. USDT moves between wallets for cents and minutes.
24/7
Fiat banks don't work on weekends. If the market moves sharply on Friday evening, you can't withdraw anything until Monday. Crypto infrastructure operates around the clock.
Stablecoin Staking
On many exchanges, USDT can be placed in flexible savings or earn programs yielding 3-8% per annum. This is not a risk-free deposit — it's lending (the exchange uses your USDT for margin lending to traders), but in calm times it works steadily. There is no such yield on a fiat account.
How This Differs from Risk-Free Storage
The main point is that a stablecoin remains a crypto asset. Risks:
- Exchange risk. If an exchange collapses (FTX, Celsius — examples), USDT on it may be lost in the bankruptcy along with the exchange.
- Depeg risk. USDT may temporarily lose its peg. In 2023, after the SVB collapse, USDC dropped to $0.87 before recovering. USDT has also been at $0.95.
- Regulatory risk. If the issuer is shut down or sanctioned, client tokens may be partially frozen.
Hygiene
Experienced traders separate: an operational amount in USDT on one or two exchanges (for trading), and the bulk of capital in a cold wallet or on regulated platforms. This is the same logic as cash vs. safe: some at hand, some secure.
