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 PLN, after all costs.
Splitting the order across exchanges brings no benefit here. Best to buy everything on Bybit EU.
For 10,000 PLN you currently get the most USDC on Bybit EU: 2,563.13 USDC. The least favourable exchange (Coinbase) gives you the equivalent of 70.44 PLN (0.70%) less.
Exchanges with a direct USDC/PLN market: Bybit EU, Kanga Global, OKX. 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, Bybit EU comes out cheapest.
Bybit EU leads both for 1,000 PLN and for 100,000 PLN, so it also has the deepest market for this pair.
Even for 100,000 PLN, splitting the order across exchanges brings no benefit, so one exchange is enough.
PLN deposits: P2P (Kanga Global); BLIK (Bybit EU, OKX).
Calculated at 21:37, with all costs included. The calculator above runs live for your amount.
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.
You can deposit Polish złoty in several ways: BLIK (Bybit EU, OKX via ZEN), P2P (Binance, Kanga Global) or a bank transfer to an exchange with PLN markets. Only some exchanges have direct PLN markets (including Bybit EU, OKX and Kanga Global); the rest require conversion to EUR or USD, which the calculator prices at the ECB rate plus a 0.5% spread. Buying by card is convenient but usually costs 2–5%.
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.
