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.

FlatexOur Opinion

For investors who want crypto exposure inside a conventional brokerage account alongside shares and ETFs – complete with German tax reporting and a familiar interface – flatex is a solid choice. If you want to own real coins and withdraw them to your own wallet, you need an actual crypto exchange instead.
