Verdict
In our overall rating Kraken Pro leads with 4.4 against 2.5 for BISON.
On a €1,000 purchase you pay €8.40 less at Kraken Pro.
For most investors Kraken Pro is therefore the better choice.
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.
Kraken Pro is the separate trading interface from Kraken (pro.kraken.com and Pro mode in the mobile app) and is aimed at active traders. Unlike the standard platform with flat 0.99% fees, the volume-based maker/taker model applies here, starting at 0.25% maker and 0.40% taker, decreasing as 30-day volume rises. Account, verification, and asset balances are shared between both interfaces.
The order set covers market, limit, stop-loss, take-profit, trailing stop, iceberg orders, and bracket/OCO combinations. Margin trading is offered with up to 5x leverage depending on the pair, with selected assets reaching 10x. The availability of margin and derivatives is tied to MiFID II requirements in some EEA countries and is handled via Payward Europe Digital Solutions. Charts, order book, and API access (REST and WebSocket v2) are described in user reviews as sufficient for active strategies; the learning curve compared to the standard interface is occasionally criticized.
Kraken Pro is considered particularly suitable for active traders who value pro order types, lower volume-based fees, and margin features. Those primarily looking for savings plans or simple spot investing will find a more fitting setup on the standard interface. This comparison does not constitute investment advice.
