Find out where you can do it. We compare live order books of 10 exchanges and show how much USDC you really get for your USDT, after all costs.
Splitting the order across exchanges brings no benefit here. Best to buy everything on OKX.
For 2,500 USDT you currently get the most USDC on OKX: 2,493.43 USDC. The least favourable exchange (Coinbase) gives you the equivalent of 11.69 USDT (0.47%) less.
Exchanges with a direct USDC/USDT market: OKX, Binance, Bitstamp, Kraken, Kanga Global, Coinbase. 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.
For 250 USDT the best is OKX, for 25,000 USDT it is Bitstamp. With large amounts order book depth matters more than the headline rate.
Even for 25,000 USDT, splitting the order across exchanges brings no benefit, so one exchange is enough.
You deposit USDT with a crypto transfer from another wallet or exchange; the sender pays the network fee.

USD Coin (USDC) is issued by Circle; it is MiCA-compliant, so it is available on all licensed exchanges in the EU. It works well as an intermediate currency: many exchanges have cheaper USDC markets than fiat (e.g. Bitvavo charges 0.05% on USDC markets). Withdrawals are possible on many networks (Ethereum, Solana, Base and others), and the cost depends on the network you choose.
Paying with USDT means depositing it by crypto transfer from another wallet or exchange. Choose a network the receiving exchange supports and double-check the address and memo. USDT pairs are deepest on global exchanges (Binance, OKX), while MiCA-licensed exchanges may not support it.
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.
