OKX cheapest exchange to buy Bitcoin among MiCA platforms

Anyone wanting to convert €1.000 into Bitcoin and then transfer it to their own wallet will find the cheapest option at OKX. This is the result of a comparison by DefiLlama that takes total costs into account: SEPA deposit, taker fee, order book slippage and Bitcoin withdrawal fees. Among the MiCA-certified exchanges, OKX scores by far the best with a total price of just €2.44.

Bitcoin is available at OKX and Bybit.

Big cost differences between exchanges

The differences between the platforms are remarkably large. Kraken comes in second place with €5.44, followed by Bybit at €7.31. After that come Coinbase (€13.93), Backpack (€14.00) and Gate (€14.76). The tailender is Crypto.com, where the same transaction costs as much as €30.60. That is more than twelve times more expensive than OKX.

OKX is thus €3 cheaper than Kraken and almost three times as affordable as Bybit. Anyone who regularly buys Bitcoin and withdraws it to their own wallet can save significantly over time by consciously choosing an exchange with low total costs. If you want to benefit from extra discounts, you can also look into an OKX referral code or a Bybit referral code.

MiCA as a framework for the comparison

The comparison specifically focuses on exchanges that operate under the European MiCA legislation. This makes the data extra relevant for European users, because all these platforms meet the same regulatory requirements. The costs you pay are therefore purely the result of the platform’s own fee structure, not of extra compliance costs.

It is striking that exchanges are now particularly in the spotlight when it comes to costs and competition. For instance, exchanges in 2026 also attract the most venture capital money within the crypto sector, showing how competitive the market has become. Low costs are an important differentiating element in this. For consumers, it therefore pays not to automatically choose the most well-known name, but to seriously consider total transaction costs.
