BISONOur Opinion

BISON is the crypto app of Börse Stuttgart and is perceived in the DACH region as a provider with a traditional capital markets background. Crypto custody is handled by Boerse Stuttgart Digital Custody GmbH, which is regulated by BaFin. With 26 tradable coins, the selection is clearly limited compared with specialized crypto exchanges.

As one of the few offerings among German brokers, BISON allows free wallet transfers to your own wallets. Staking, savings plans, and an integrated tax report are also available. Deposits are possible via SEPA, instant bank transfer, and credit card.

The trading fees of 1.25 % are in the upper range of the brokers compared and are occasionally criticized by users. The exclusively SMS-based 2FA and the processing time for wallet transfers of up to 24 hours are also seen as room for improvement. Overall, BISON is aimed at investors who prefer an established German provider and are willing to accept trade-offs in fees and coin selection.

OKXOur Opinion

OKX is considered one of the first crypto exchanges with a fully fledged MiCA license in the EU and is valued for combining regulatory compliance with low fees. With trading fees of 0.35 % and total costs of just 1.10 € per trade, OKX is among the cheapest providers in the comparison. The availability of proof of reserves is positively viewed by security-conscious users.

The selection of 270+ cryptocurrencies is room for improvement compared with some competitors with over 600 coins. The KYC process with eID and photo ID is also occasionally criticized as time-consuming. However, the extensive payment methods — including PayPal, Apple Pay, and Google Pay — are seen as practical.

OKX is particularly suitable for cost-conscious investors who prefer an EU-regulated platform with a MiCA license and low trading fees and are willing to make compromises on coin selection.
