Find out where you can do it. We compare live order books of 10 exchanges and show how much USDT you really get for your USD, after all costs.
Splitting the order across exchanges brings no benefit here. Best to buy everything on OKX.
For 2,500 USD you currently get the most USDT on OKX: 2,499.88 USDT. The least favourable exchange (Binance) gives you the equivalent of 87.66 USD (3.51%) less.
Exchanges with a direct USDT/USD market: OKX, Kraken, Crypto.com, Bitstamp, Coinbase, Kanga Global, Binance. Elsewhere you need a currency conversion or an intermediate currency, which usually adds cost.
Counting only the trading fee and slippage, Bitstamp wins, but once deposit, conversion and withdrawal are included, OKX comes out cheapest.
OKX leads both for 250 USD and for 25,000 USD, so it also has the deepest market for this pair.
Even for 25,000 USD, splitting the order across exchanges brings no benefit, so one exchange is enough.
USD deposits: Card (Binance, Coinbase); SWIFT (Kraken, Bitstamp); ACH (Coinbase, Crypto.com); P2P (Kanga Global); Revolut account (Revolut X).

Tether (USDT) is the largest US-dollar stablecoin. In the EU, under MiCA, licensed exchanges restrict USDT trading (e.g. Bitvavo does not list it and Bybit EU has no USDT pairs), so you have fewer exchanges to choose from. When withdrawing, pick the network your receiving wallet supports (e.g. Tron, Ethereum): network fees can differ more than tenfold.
Outside the US, dollars are usually deposited by SWIFT wire, which has a fixed fee and takes 1–3 business days; US customers can use ACH. USD and USDT/USDC markets are the deepest in the world, so for large amounts the dollar is often the cheapest route. If your bank converts at a worse rate than the ECB, also check the route via EUR.
Enter an amount in any of 30+ currencies (dollars, euro, pounds, złoty and more) or in stablecoins, and choose what you want to buy: Bitcoin, Ethereum, USDT or USDC.
We pull hundreds of live offers from every exchange and check every buying route, including currency conversion and intermediate currencies, e.g. GBP → USDT → BTC.
Slippage for your amount, trading fee, currency conversion, deposit and withdrawal. No hidden costs and no comparing headline rates alone.
You get a ranking with the exact amount you will receive and, for large orders, the optimal split across several exchanges.
We pull data directly from the exchanges’ public APIs. More exchanges and cryptocurrencies are coming.
According to our ranking of 10 exchanges: for 250 USD it is OKX; for 2,500 USD it is OKX; for 25,000 USD it is OKX. The answer depends on the amount, because market depth matters for larger orders.
The total cost on the best exchange (OKX) is about 0.14% of the amount: fee, slippage, conversion and withdrawal. On the most expensive one (Binance) it is about 3.64%.
